Not sure if it is useful or even practical but:
Would there be any good in the ability to clone a conversation (i.e starting a new one from a copy of an old one)? Say I'm in long-running conversation 1, then I want to do some experimental stuff so I fork off long running conversation 2 as a clone of the first one.
I click along and later decide that it was no good so I "rollback", i.e. go back to where I was on conversation 1. "commit" would then be just to continue on conversation 2.
Or would it just be a mess?
