When using Mail with Gmail IMAP, how to move emails to different folders and not label them? I'm using Mac Lion Mail app with Gmail IMAP and when I drag and drop or command-click to move messages from my Inbox to a folder called Personal, it appears to work in Mail.  But when I look at Gmail, the message remains in Inbox.  Instead of actually moving the message, it simply gives it the label, Personal.  

In Gmail, I never label anything, I always move messages to various folders and I want to mimic this behaviour in Mail app.  How can I do this?
Gmail has a guide on how actions on IMAP clients correspond to Gmail actions. In order to remove items from your inbox in Gmail, you will need to delete them from your inbox in Mail.app -- this will "archive" the message in Gmail rather than moving it to the trash. The trouble with this is that emails that you move to a folder in Mail.app probably won't show up in your Mail.app inbox until you refresh it, so it may take a few steps to move and archive a message. Unfortunately, Gmail behaves so differently from normal mail services that using it with a standard IMAP client tends to be a pain. However, the reference in the link above should help you figure out which actions in Mail.app correspond to various Gmail actions.
