Oops, entirely misread the first issue, yeah I know of them being misplaced, that's due to me re-using the Winamp3 styled things for everything, and the pre-made buttons have their text not properly aligned, which causes some weird stuff like with the arrow buttons.
I could make my own button implementation, but that'd be too much for something so simple (as I do intend on keeping the skin size small)
I'm already aware of the playlist item moving issue as it only ever seems to do the currently playing title (there also doesn't seem an API that moves the selected items, only the currently playing one), as for the other issue, I'd need a screen recording to fully know what's going on as I don't really understand what's up.
