Gmail rolls out tools to make labels easier
Here's the idea. Instead of clicking the "more actions" button to apply a label and then hitting the archive button to move a message out of your inbox, you'll be able to just hit a "Move to" button in the Gmail toolbar. If you want to add a label without removing the message from your inbox, you can just select the "Labels" drop down menu instead.
The new feature is expected to roll out for all users soon, but the new buttons haven't shown up for any of my Gmail accounts yet.
