The actions of FIlling and Un-Filling Zones are not undoable.

[Chris Goddard]

The actions of Filling and Un-Filling Zones are not undo-able.

Every action should be part of the undo/redo stack, it's the natural way to revert something if you change your mind or make a mistake. With the way it is at the moment if you undo after a fill then you undo the action prior to that fill. This could be interpreted as undo not working and lead to the undo going unnoticed.

It's been suggested that this is not necessary as un-fill is the reciprocal of fill, so why do you need undo. This logic could be extended to any tool in that case and means the user has to remember that some are 'special' and can't be undone. Not very user friendly. Best to have one way of working, universally.

Because some parts of zone fills are automatic (as the outline changes) but other parts are not (such as knock-outs for other features), and undo would be at best ill-defined.
