// @name          Bloglines sidebar tweaker
// @namespace     http://lieschke.net/projects/greasemonkey/
// @description   Squeezes the feeds in the Bloglines side panel so that as many as possible are visible at once. Removes the tabs at the top of the side panel. Moves the Add/Edit/Options links and Extras into a drop-down at the bottom of the feed tree. The sidebar display can be customised through the Tools --> User Script Commands menu. Adapted from http://www.allpeers.com/blog/downloads/bloglines-sidebar-squeezer.user.js
