Hide elements, and go fullscreen.
I'm a minimalist fan :) The option to hide the sidebar and header and take the reader view fullscreen would make this my go-to app. Otherwise, great work!

Picture this: a 800x480 res netbook (EeePC 7") with Google Chrome and "side tabs" flag activated. Most of my screen is the site's interface.
Fullscreen option (maybe with very minimal buttons and toggle options for both sidebar and header) would be awesome.
