Feel free to add my Feedly Theme: viewtopic.php?f=22&t=2065
The special thing about this theme is that it's themed from scratch. It doesn't depend on fox's CSS and won't break if he does CSS changes.
Another speciality: It comes with a claro.css modification (the dijit theme used), so preferences look clean, flat and monochrome, not glossy and blue.
All layouts, default plugins and preferences are themed. I use it daily on Chrome with the latest TTRSS-Code from GitHub while trying not to break old versions, especially the currently stable one.
