First off, I don't have access to Mavericks, this a question for the people who do. Even since the Archive button was introduced in Lion Mail, I've been hoping that we'd be able to map that button to function the way Archive does in Gmail (remove the "Inbox" label, but keep the message in "All Mail"...keep in mind that I want the delete key to move messages to the trash in this scenario, as well). Currently, the Archive button, when used with Gmail accounts, will create an "Archive" folder (really a label) in the gmail account, and add that label to any message highlighted when clicking the "Archive" button. Any chance this behavior is changed in Mavericks? Can we map what we want the Archive button to do, or is the behavior the same as Lion and Mountain Lion? I prefer to use Mail as my only client (I hate webmail interfaces and only use them when away from my machine), but find myself falling back to Sparrow or AirMail when dealing with my Gmail accounts because of the way the Archive button works in those programs.
