I think that it would be nice to have the ability to move (not [S]ave) a message to another folder in a single atomic operation, without having to [$]Synchronize. (Assuming that the current folder is a Maildir, where moving a message is just moving a file.)
In my conceptual model of e-mail, I view each message as a task to be done (e.g. I have to reply to the mail, or the mail is telling me to do something, etc.). So, it makes sense for me to keep my inbox clean so that it only contains messages that I still have to "do something" about. Any messages that I have finished, I move them into my "done" folder. It would be convenient to be able to use a "Move" command in mutt that immediately moves the message into the "done" folder (on the filesystem level, it's just an "mv" from one Maildir to another) and immediately makes it disappear from the message list of the current folder. Right now, I have to [S]ave then [$]Synchronize, which takes longer. Thoughts?
