I would like to request for a polygon selection undo... now, undo is only for the polyline... please add for the selection tools... I may suggest that you look into how GIMP does its selection where freehand and polygon is combine into one which is (for me) the most powerful selection method present even against the big boys like photoshop... thank you... Reproducible: Always
and also tackle new selection, add, subtract and intersect with just a new selection, shift, alt and ctrl keys respectively...
+1 from me, in recent beta the Shift + Z shortcut for undoing polygon selection is not working. also @Manson Mamaril you can add subtract and replace selection by pressing A S and R respectively.
this seems to be fixed in recent 2.9 beta. Can't reproduce it. Shift + Z (undo polygon points) is working again.
This bug has come back again now
