Ok, this feature is good.
I’ve always preferred using the Gmail webmail interface, it just makes everything so much easier.
Now Google has added a smart Priority Inbox that lifts separates important and starred emails out of your general inbox. It is easy to swtich on and use, and it works really well. Just like Google’s spam reporting, you can mark the emails that should / should not be in your priority inbox, and the system learns.
If you are already using Google Apps, you should see a red Priority Inbox link near your Settings link at the top right of your inbox. If you are using Outlook or even Apple Mail, watch this video and maybe consider the zen of Gmail.
