Edit: FA no longer has a sidebar. Huzzah! This extension is no longer available.

For everyone who's running beta and hates the new sidebar on submissions:

If you run chrome, you can disable it with this extension I made: [edit: deleted]
1) Download and extract somewhere.
2) Go to chrome://extensions
3) enable developer mode
4) choose 'load unpacked extension'
5) open the extension (go to the map you extracted and open)

Note 1: It appears to screw up the reply-indent.
Note 2: it sucks big-time if the sidebar is bigger then the comment-section.
