v0.3.0 - Genre Search

• Added ability to search through all genres in your library on the genre selection screen, rather than being limited to relevant/recommended genres
• Added "start over" button to the album results screen, to restart from the beginning and select different preferences (can also start over from any screen before seeing results)
• Enhanced user interface for mood selection screens, to make current selections clearer and navigation more consistent
• Transition to/from album results screen now uses a crossfade animation instead of an immediate cut
