Hi Radim,

well, probably the way how does it work currently is not really ideal.
In my previous post (reply to Tim) I've suggested another possibility,
hopefully easier to comprehend. However now I'm not sure if that won't
bring any drawbacks.

I see one problem: e.g. GRASS edit has its own set of map tools. The
question is what to do when grass edit ends - what tool to activate:
Leave map canvas without any tool? Set panning tool as active? If so,
how to get the pointer to panning tool to make sure that button
associated with the tool will be activated?
