Remove the (irrelevant) ads sidebar from Gmail message view allowing more width for the actual message.

Several customizable options. Special support for Userscripts.org (new interface, fix for pre tags, and allows you to hide the install warning box and footer) Changes text fields, buttons, links, selects, and text areas.

For new version of Gmail: when viewing a message/conversation, the advertisement box on the right is removed and messages and reply box occupy the full width available. Long titles are optionally truncated.

Read and write using a monospaced font in Gmail's basic HTML view.

Removes the stupid fixed-width design

Make the content on edge.org pages use full page width available
