Didn't notice that was part of the thread.
In the video, when you replace your UIFooSprites with UISprites it seemed to remember the previous settings such as atlas and sprite. However, that is not working for me, which caused me to roll back to 2.x because, well, yeah. Is there some trick or sequence to get the settings to restore when changing the scripts? I am on 4.3.2 on OSX if that makes a difference.
Edit: You should also add something about UIDraggablePanel to that post. And there really should be a sticky just for the upgrade procedure, as it's like, a really big deal and kind of important. A place for people to add their experiences and tips would be helpful as well.
