I've been using this dor about 18 hours or so and I have already noticed a few problems.
First, while in Phablet UI if I swipe down right from cennter on my status bar it opens the quick settings menu. The problem being that I have both quick pulldown and quick settings disabled. Notification menu opens as expected if I swipe down left from center.
I need to copmetely disable the quick settings menu, It's useless if I'm going to use the power toggles in the notification tray.
Second, if I even attempt to use Phone UI after using Tablet or Phablet UI, I get an error almost immediately, and the system UI forcecloses.
