Yes, we plan to implement undo/redo (in fact it is being worked on as a low priority background task). As I mentioned it’s a matter of integrating the internal model versioning changes made for pyGPlates back into GPlates. It’s not trivial though, and it’s low priority because users can use the `reload` button (in `Manage Feature Collections` dialog) to undo changes (although understandably it’s much better to have proper undo/redo).
