Confirmation before removing node in task tree
For the moment, removing a node (using the Delete key) is applied without confirmation, and without any way to undo this effect. There should be some protection:
- asking for confirmation with a dialog window, as in former IDE ? but could become painful now...
- option: configure whether such a confirmation should be asked in the preferences, as it is done already for saving session at exit?
- or: implement some "undo" feature: seems really hard with the current implementation of sessions
- or: implement a temporary "trash" directory for recovering
