I will be kinda disappointed if there still have choppy transitions and animations in beta 3 after fixing them for almost a month. Well we'll see what happens.
The only real change they did in beta 2 vs beta 1 was bring back the 6th icon on the drop down menu, then in beta 2 they removed the option to set a day/time to auto restart
Someone posted earlier from SamMobile they were having an issue and needed more time to send out the next beta. I doubt we are getting any new features this close to stable release.
