In Frodo I noticed that when you remove a source and when it asks if you want to remove the items from the source from the library it doesn't give any progress indication while it does that. In Eden, I'm pretty sure there was progress indication. Without that indication it can appear as if xbmc has locked up, especially on a source with a large amount of items. Not sure if it's removal was intentional or not.
Anyway, just something noticed so throwing it out there.
