I know that a procedure based on backups and something like zc.beforestorage is going to be better. It's also an order of magnitude more difficult for people to set up and recover from. I think we'd see a pretty big backlash if we just removed the Undo feature, imperfect though it is. Unfortunately, I think the people most likely to have used it in a pinch are less likely to be reading this list. If the current API is broken, we should fix it. If that means fixing some of the UI in Zope to use a new API, that's OK too. Few people will have customised this or relied on the "old" API. If we had to say you only get step-by-step undo from the most recent transaction, then that'd probably be OK too. In this case, we should have a UI that lets you specify a number (undo N transactions) or a limit (undo up to and including transaction X). I think people understand that undoing a single transaction that's not the most recent one is error-prone anyway.
