I like the GTD way of managing mail, and I’ve created folders for this. The three folders I use the most are AA Next Action, AA Waiting, and Done. Dragging messages down to the right folder is more mouse work than I like, though. I created three buttons on a custom toolbar. For example, the action that moves the current message to my Done folder runs this:

@Command([Folder]; “Done”; “1”)

I’d love to associate these with keyboard shortcuts, or spend some time hacking my mail template. That would be even awesomer! =)
