Nice, you could also capture 3d forms, turning around objects or people, or mapping real textures, looking at your meshes through what is in front of you.
I had many problems when those changes was made, such as zooming and panning both in 3d views and Image editor, zooming and panning in 2d editors (node, clips editor, etc.), panning in the panels header, zooming at cursor position, and so forth.
Now I managed to restore the most of functions but 2d views navigation.
Moreover multiple loop cuts doesn’t work anymore, and maybe other issues I don’t know, because I cannot work with such latest revisions, and I have to stick to 2.65a.
