Another new feature in 1.3 will be the ability to use album art as the background image for GMMP. Opacity can be set in the settings along with the image to use when there is no album art present (options are the gradient or black)
|Note: the Background setting was moved from Now Playing to UI|
Video showing the transitions. Note: the video is laggy because of the recording software I used on my phone. Normally transitions start instantly.
One other thing added is an option to turn off the default album cover when album art is missing (the GMMP logo which I know doesn't look very good)
