Priority Inbox
Google is rolling out a new filtered view of your Gmail inbox—‘important & unread’ messages will float to the top, above starred messages, with ‘everything else’ at the bottom.
Early reviews suggest it works well, and works with your existing filters.
As far as I can tell, though, Priority Inbox only works if you use Gmail’s web interface, rather than, eg. adding a new IMAP folder for the important stuff, leaving those of us who like to download our mail and read it in a client out in the cold.
