Flash Features
Flash all, selected, or individual features on the map canvas — from the Layers panel, attribute table toolbar, attribute table right-click menu, or the plugin toolbar.
Adds quick "flash" actions in three places:
Plugin toolbar (two buttons):
• Flash selected features — flashes selected features on the active layer (red)
• Flash selected vs rest — flashes selected features red and all other visible features blue simultaneously
Layers panel context menu (right-click a vector layer):
• Flash selected features
• Flash selected vs rest
Attribute table:
• Toolbar buttons — same two actions as above, acting on the table's own layer
• Row right-click — "Flash this feature" flashes the individual row you right-clicked
• Hover — moving the mouse over a row flashes that feature (debounced, 120 ms)
Compatible with QGIS 3 (Qt5/PyQt5) and QGIS 4 (Qt6/PyQt6) via runtime detection.
No external dependencies.
