Sorry but this new Sync manager is an absolute mess....why o why you decided to change the side by side layout on V2 i will never know? Reloading my iTunes in V3 doesnt load any playlists, so its only my old V2.2 that I can use now...and even that is kinda broken thanks to the bridge feature not working in Yosemite.
Youve messed this up...big time
