Nice music player you've made there =] The UI is clean and easy to use, gestures are handy, action bar is handy, and nice floating music controls for multi-tasking.
I do get FC when I add a folder to shortcut and go to the main menu to scroll down. The FCs stop when I remove the shortcut so it doesn't FC until I scroll, long-pressing to remove shortcut is possible.
I also notice that if I have a folder with some loose files + folders with music in it, the adding to playlist feature only adds the loose files and not the folders, is there a setting to change that?
If I may, I have a request, since it is a folder player, is it possible to add "play folder (and subfolders)" without opening it or making it a playlist? Also, could you add screen rotation capability to use the player in landscape mode?
Thanks for your great work!
