I agree this would be the right thing for a real undo mechanism.
But how useful would it be? I’ve never been in a situation where
rollback/switch-generation would be insufficient or inappropriate.
I’m concerned that this would add both code and user interface
complexity for mostly hypothetical use cases. WDYT?
Thanks,
