Written by Lifehacker editor Gina Trapani, the extension is basically a collection of her favorite Greasemonkey scripts. It does more than just slap your feeds onto the bottom of your in-box, though. It adds a Collapse/Expand Gmail link to the top-left nav, just under the Compose link. This hides your e-mail and pulls the Reader up to the top, and swtiches to Expand when the in-box is hidden. It also adds a control panel to central left nav for managing your feeds, a neat work-around so that you can collapse the Reader's built-in navigation. The Reader pane is collapsible, too, so you can hide the perpetual distraction of feeds from the perpetual distraction of e-mail.
You can get more extensions to add folder like hierarchic to your GMail labels. But all these cool things will only be accessible if yo are browsing your Gmail on FirFox and have installed the set of extension packed in these exe.
