what about to assign doGotoNextSong and doGotoPreviousSong to holding volume buttons, did it and it works. now i think it would be good to have direct start and stop playing buttons. but i dont see doFunctions for that

maybe we should use doEnterHold for this?
Update doGotoNextSong and doGotoPreviousSong can be used to start music too. so we can assign doEnterHold to stop play. (only i dont know how to do it, maybe main.xml needs editing?)
