MatchFeature
Copy attributes and visual style from one feature to others in the same layer, in two steps (inspired by AutoCAD's MATCHPROP).
MatchFeature brings the "match properties" idea to QGIS. It works in two simple steps inside a single editable vector layer: (1) select ONE source feature and click the button to COPY its attributes; (2) select one or more target features and click again to APPLY those values to them. It copies every editable field while skipping identifier/auto-increment columns (fid, id, id1, gid, objectid, *_id, ...) and read-only fields, and for Categorized/Graduated styles it copies the classification attribute so targets inherit the source symbol. Incompatible fields are skipped silently, the source feature is never modified, and the whole apply step is a single Undo (Ctrl+Z). Works with point, line and polygon layers. Idea & design by Hugo P.
