This is THE companion to iTunes, and I've used them all, PTHNotifier, Synergy and even youControl. It still lacks hotkeys and some polish though (I can't get it to auto-share covers with iTunes, having to do it manually). Especially in the documentation area. It NEEDS pop-up context help labels (WTF do that lock-icon do?). It could do with hue-adjustment of the skins (I love the snow-skin, but would like a more graphite top), like Audion.

And what's with that warning that pops up in the background (usually behind a window) asking if I want to share the cover with iTunes that I can't get in the front. I've often forced quit Sofa thinking it was crashed. Oh, and when choosing a cover manually from web services the menu will not go away when trying to apply the cover. I have to open it manually and drag it to the cover box (triggering another hidden alert).

This may seem like ranting, but I really love this software and would like to see the bugs go away ASAP. It's gotten better though. It used to be completely unusable. Now I can't live without it.
