A bug I've found…
using the auto playlists, condition "is any of". when you click the drop down menu to select the ones you want as soon as you click on one, the drop down menu closes.
eg: auto playlist - genre is any of <aac,alac>. as soon as I click on aac, the drop menu closes and I have to reopen it again to select alac. In 2.x you could select all the choices you need before chosing the drop menu
