Folks, I want to take some small steps to providing Undo features in O.
A full featured undo is not really feasible, but we can do some rather simple things that help quite a bit. The obvious first thing is to be able to undo an accidental drag of a waypoint.
The problem is the Ctrl-Z key is already assigned to do a zoom. We have zoom on +/-, the scroll wheel
, the toolbar and even pinch-to-zoom if you have multitouch. And Ctrl-Z as undo is probably one of the most standard key assignments in the entire computer industry.
So unless someone comes up with a really good argument why we should keep it being zoom I will be changing it to become Undo.
