## [0.15.13] - 2026-08-12

### Changed
- **Reverted 0.15.11's two-column field layout in the Charts tab.**
X/Category + Y and Group/Color + Value/Size are back to one field per
row each, as they were before.

## [0.15.12] - 2026-08-12

### Changed
- **Reverted 0.15.11's shorter tabs** back to the original height, and
widened them by the requested 1.2× instead.
- **Brought back a clear "this tab is open" indicator** — a small teal
dot icon on the active tab, instead of 0.15.9's border accent stripe.
Tab icons are a native `QTabBar` feature Qt paints in its own
dedicated slot, so it can't collide with this tab bar's native-theme
box-model quirks the way a border property did.

## [0.15.11] - 2026-08-12

### Changed
- **Shorter, wider tabs.** The tab strip's vertical padding is cut
roughly in half (33px → 19px tall) and the horizontal padding is
increased — direct feedback on the tab row's proportions.
- **Paired field pickers in the Charts tab.** X/Category + Y, and
Group/Color + Value/Size, now sit two-up in one row each instead of
four separate full-width rows, saving vertical space in an already
long Chart card.

## [0.15.10] - 2026-08-12

### Fixed
- **Reverted 0.15.9's accent-stripe border on the active tab.** A real
screenshot showed it covering part of the tab's text with a white
strip, not highlighting it — this native Windows tab style had already
shown once (0.15.6) that it doesn't reliably honour a custom QSS
border addition, and the accent stripe turned out to be another
instance of the same problem. The active tab is shown with a
background/text-colour difference again, exactly as it was in every
release before 0.15.9, with no border property on this tab bar at all.
Tab widths remain proportionate to each label (unchanged from 0.15.9 —
that part wasn't the problem).

## [0.15.9] - 2026-08-12

### Changed
- **Redesigned the tab strip.** Each tab is now sized to its own label
instead of every tab being forced to match the widest one ("Diagrams")
— the shared minimum-width fix from 0.15.8 fixed the fit, but made the
two shorter tabs ("Charts", "Labels") look oversized and out of
proportion. The active tab is now shown with a clean teal accent
stripe along its top edge — a clearer, more conventional way to signal
"this one is open" than relying on a size or colour difference alone,
and it holds the same reserved thickness whether selected or not, so
choosing a tab never resizes it.

## [0.15.8] - 2026-08-12

### Fixed
- **Tab labels are correctly sized on every machine, not guessed.** A
second real screenshot showed "Diagrams" and "Labels" still losing
their last letter to the ellipsis fallback, meaning every fixed
padding value tried across 0.15.2–0.15.7 still came up short against
real desktop font rendering — this project's offscreen test harness
simply can't reproduce the exact metrics of a real Windows session
closely enough to pin down the right constant by trial and error.
Instead of another guessed number, the tab bar's minimum width is now
measured at runtime from `QFontMetrics` on the actual font Qt is using
on your machine, with a generous safety margin added on top — it is
derived from the same measurement Qt itself uses to paint the text, so
it cannot be wrong about its own labels' width regardless of font,
size, or DPI. Verified against four very different test fonts/sizes to
confirm the value tracks whatever is actually active rather than
assuming one specific font.

## [0.15.7] - 2026-08-12

### Changed
- **Tabs are noticeably bigger than their own text**, not just barely
fitting it.
- **Removed the toolbar's separate "About" icon.** Its content already
lives in the dock's own Guide — a second icon was pure redundancy.
- **The Guide now links to the online documentation site** (a small "🌐
Online docs & manual" link in its sidebar, always visible while
scrolling).
- **Histogram axis labels are rounded** to at most 3 decimal places
instead of Python's default 6-significant-figure formatting, which
could produce long, unreadable numbers for small-magnitude fields (a
0–1 ratio field, for instance) and made the chart hard to read.

### Fixed
- **Suggest on a wide/tall layer no longer pulls every field into
memory before even deciding whether to sample.** The 0.15.4 fix
bounded the O(fields²·rows) correlation *scan*, but a report of the
crash recurring twice more showed that wasn't the whole story: pulling
every column of a genuinely wide grid/zonal-statistics layer into
Python for up to 100,000 rows was itself heavy enough to strain
memory, before any analysis began. The field count is now checked from
cheap layer metadata and bounded up front — 60 numeric fields by
default, 300 if you explicitly choose "Scan the full dataset" —
independent of, and in addition to, the existing scan cap.

## [0.15.6] - 2026-08-12

### Fixed
- **Found the actual cause of the tab-label clipping**, from a user
screenshot rather than another guess: every tab was missing its *first
letter* — "Charts" read "harts", "Diagrams" read "iagram", "Labels"
read "abels". That is a known Qt/Windows quirk: the native Windows tab
style paints tabs through the real Windows theme engine, which
reserves its own internal left inset that a custom stylesheet doesn't
fully override, so the leading glyph gets painted under the tab's
rounded left edge. This project's offscreen test harness has no native
Windows theme engine to reproduce it against, which is why the
previous few rounds (width, padding, label length) all missed the real
mechanism. Fixed with extra left padding on each tab plus a small
leading space in the label text — whatever gets eaten from the left
edge is now blank space, never a real letter, regardless of the exact
pixel amount. (An attempt to force the tab bar onto Qt's own Fusion
style — which draws purely from the stylesheet and would have
sidestepped the native theme rendering entirely — was tried and
reverted: it segfaulted on dock teardown and didn't reliably apply
anyway, likely from mixing an explicit style override with the panel's
own stylesheet-driven style proxy. Not worth the crash risk for an
unproven fix.)

## [0.15.5] - 2026-08-12

### Changed
- **More breathing room in the tab strip.** Each tab's padding is more
generous again (without reintroducing 0.15.2's fixed minimum width, so
tabs still shrink to fit any dock size instead of running off the
edge).
- **Suggest asks first on a wide or tall layer.** If the layer has
enough numeric fields or rows that the correlation search would
otherwise be limited to a sample, Suggest now shows a short dialog:
use a fast representative sample (recommended — the previous, silent
default) or scan the entire dataset, with a plain-language note about
what that trade-off means. Either way, the result now says which one
was used, and a sampled result invites you to Suggest again and choose
the full scan.

## [0.15.4] - 2026-08-12

### Fixed
- **A real regression from 0.15.2/0.15.3.** Forcing the tab strip to
expand and hold a fixed minimum width meant Qt kept it at that size
even when the dock was too narrow to show it — and with the panel's
horizontal scrollbar disabled (from the earlier scrollable-panel fix),
the overflow simply ran off the right edge with no way to reach it.
That is worse than the original "tab looks tight" complaint: a real
user report confirmed part of the "Diagrams" label was being clipped
mid-letter. Tabs are back to their natural, always-fit width
(verified: every tab's text fits its own box at every dock width from
140px to 600px) with an ellipsis fallback for a genuine edge case, and
the panel's horizontal scrollbar is now shown whenever something
actually needs it, so nothing can become silently unreachable again.
- **The real cause of an oversized panel.** Two tab intro sentences
("Draw a diagram on every feature…" and "Turn fields into well-placed
labels…") were missing word-wrap, so Qt sized them to fit their
*entire sentence on one line* — over 1000px each — which alone was
forcing the whole studio panel more than 1500px wide. Both now wrap
normally.
- **A crash/hang risk in 💡 Suggest on wide layers.** Scanning every
pair of numeric fields for the strongest correlation is quadratic in
field count. A typical layer has a handful of numeric fields and this
is instant, but a grid or zonal-statistics layer can carry dozens to
hundreds of derived numeric columns over up to 100,000 rows —
uncapped, that is hundreds of millions of pure-Python operations run
synchronously on the UI thread, which can read as QGIS freezing or
being killed outright rather than a slow click. The scan is now
bounded to an evenly-sampled subset of rows and the first 40 numeric
fields, so Suggest stays fast and safe regardless of the layer's width
or height.

## [0.15.3] - 2026-08-12

### Changed
- **The Map diagrams tab is now labelled "Diagrams" in the tab
strip.** Even with 0.15.2's wider, evenly-shared ribbon, the full "Map
diagrams" label could still run tight against real desktop font
metrics on a narrower dock. A shorter label removes the dependency on
exact dock width or font rendering entirely — the tab's own card and
the guide still say "Map diagrams" in full. A text-elide fallback
("…") is also set, so any future overflow degrades gracefully instead
of silently clipping.

## [0.15.2] - 2026-08-12

### Changed
- **The tab ribbon (Charts / Map diagrams / Labels) now fills its full
width.** Each tab used to be sized only to its own text plus a little
padding; the three now stretch evenly to use the whole row, so the
longest label ("Map diagrams") gets generous room instead of a tight
fit.
- **Render chart gets a visual accent.** The button carries a soft
salmon ("yavru ağzı") stroke around its usual teal fill, so the
studio's single most-used action stands out from the row of
export/suggest buttons around it.

## [0.15.1] - 2026-08-12

### Fixed
- **The dock content was squashed instead of scrolling on a short
panel.** Docking the studio narrow/short (or on a small screen) simply
compressed every row instead of letting you reach the rest — the panel
is now wrapped in a scroll area, so it still stretches to fill a tall
dock exactly as before, but scrolls when there isn't enough height
instead of clipping the bottom rows away.
- **The selected tab's label looked clipped/unreadable.**
`QTabBar::tab:selected` set a bolder font weight than the unselected
tabs, but Qt sizes each tab's box once from its normal-weight text and
does not re-lay it out on a pseudo-state change — so the wider bold
glyphs of the active tab (worst on "Map diagrams") overflowed the box
they were already sized for. All three tabs now use the same font
weight, so the active tab is still clearly highlighted (background +
colour) but never grows past its own label.

## [0.15.0] - 2026-08-11

### Fixed
- **Toolbar icon needed two clicks to open the studio.**
`iface.addDockWidget()` already makes a freshly created dock visible,
so the old toggle handler's `setVisible(not isVisible())` ran against
an already-visible dock on that very first click and immediately hid
it again — the user had to click the icon a second time to actually
see the panel. The first click now always shows the dock; every click
after that toggles normally.

### Added
- **Proportional-symbol map diagrams.** The Map diagrams tab has a new
"Size by" field: pick a numeric field and every feature's diagram is
linearly scaled between a small and a full-size diagram by that
field's value (backed by QGIS's native
`QgsLinearlyInterpolatedDiagramRenderer`), instead of every feature
drawing the same fixed size — the classic proportional-symbol map.
Leave it empty for the previous fixed-size behaviour.
- **Diagram opacity control** in the Map diagrams tab (was already
supported by the renderer but never exposed).
- **Avoid overlaps** checkbox for map diagrams: lets QGIS drop
diagrams that would collide instead of always drawing every one of
them regardless of space.
- **Chip label preset**: a new rounded background badge behind the
label text, alongside the existing Clean / Strong halo / Bold / Plain
presets.
