Couldn't Library and Search Nav Bar buttons merge in one and go to a combined screen with Lib, like it is now, and a search field (focused to receive typing/voice directly) integrated at the bottom?
The free button will be valuable for other proposals. Maybe for a player button as home
Will be nice also if you add some shortcut for current skin settings. Maybe like in widgets. Because right now it is a real pain to get there. More thant 5 press and the same back.
Pd. I love the potential of new skin framework, but navigation should be pulished a little.
