It's a powerful feature... and I love it! But it can be dangerous... as many other ZTree features are (Prune, macros, tagged operations, etc.)

Yep.
You better know what you do.

That would be interesting as an additional warning to the existing one. I am not sure it would however help to undo disaster.

What would be useful in time of disaster is a history log of all file and directory operations done by ZTree. It would however be a gigantic ever-growing text file and slow down operations, so I do not ZEP this idea.
