I mentioned in my earlier post that I had implemented support for Simple LastFM scrobbler and Scrobble Droid. I also spent the last few hours adding persistence while navigating throughout GMMP. For example if you are browsing the artist library and scroll halfway down to artists that begin with the letter M, then select an artist to view their albums. Before when the back button was pressed, the artist list would start from the beginning. Now the artist list will be in the exact same spot you left it (in this case over the artists beginning with the letter M). The artist library view, album library view, genre library view, and browser view will now behave this way. GMMP should also start back up in the last view you were looking at.
