Because I use TB so extensively every day I occasionally accidentally hit the Delete key or drag an email to an unintended mailbox. Because these emails are sometimes much older than the newer emails I've gotten, it makes it very difficult for me to actually inspect the erroneously targeted mailbox or the trash mailbox to determine what was erroneously moved or deleted. It doesn't seem that pressing Crtl+Z undoes the move so I was wondering if there is some other magic key combination that does. If not, is there anything in the works for a future enhancement that will add this valuable undo feature?
