I'd like to suggest an option for the lyrics.
It would be nice to have 3 - 4 lines of synced lyrics over the main player area ( in the cover artwork area into a transparent window that maybe could be moved freely to the desired position ). That way displays the lyrics the musixmatch app in the floating lyrics mode but is somehow hit and miss when it has to collaborate with Poweramp.
Alternative if that isn't possible could we have the lyrics scroll over the cover art area ?
