I got only 3 favorites on my Infuse homescreen (see attached photo) - one for movies, one for documentaries and one for tv shows (I like it simple and clean).
With one of the lastest updates, I am able to create playlists. To access the playlists I can either create a list on my homescreen or go through the library.
I don't want to add lists (as I said, I want it clean). To access the library I have to go to the settings -> library and add library to the homescreen. Then I can access my playlists (and other lists). It would be cool, if there would be a easier way to access to library - instead of always have it on the homescreen. Maybe you can add a button in the status bar (where the settings button or the update button is).
