Nothing to complex about this new feature. The genre view now will have 2 selections at the top when you select a genre: 'All Albums' and 'All Songs'. This will let you view, play, play next, or enqueue every album from a genre or every song from a genre. A similar option was added to the artist view when you select an artist. 'All Songs' will show at the top of the list and let you view all of the songs from that selected artist.
I hope to have the first beta version up for download either on sunday or monday. It'll be all of the fixes/changes with probably one of the basic color skins. A ICS skin will come in beta 2.
