Enable "Undo"
tedbarnett opened this issue · comments
User needs to be able to undo latest edits. So...
- add an Undo icon/button to bottom icon bar (on left side of bar)
- if tapped, undoes last drawing or edit to map (only edits, not move or scale map)
- ideally, can tap repeatedly to undo changes in reverse order (all the way back to the first edit if possible, but okay to only allow last 3 edits or most recent)
