The one and only reason I used the full-screen editor in WordPress <3.2 is because it was a FULL SCREEN EDITOR, i.e., I used it when I wanted as much space for writing as possible.
The fancy, shmancy "distraction free editor" in 3.2 is a big pile of useless for me.
Looking at the feedback here, lots of other people don't like it either. And the response from the WordPress folks to this negative feedback seems to be, basically, "Oh, well, too bad, we thought it was cool so there you go, somebody'll eventually write a plugin to bring back the behavior you want."
Here's a piece of feedback for you: DON'T REPLACE FUNCTIONALITY THAT PEOPLE USE THAT SOLVES A PARTICULAR PROBLEM WITH FUNCTIONALITY THAT SOLVES AN ENTIRELY DIFFERENT PROBLEM.
If y'all thought the distraction free editor was so dang cool, you could have released it as an OPTION, without getting rid of the full screen editor. Or you could have released it as a nifty plugin, leaving the original full screen editor intact.
I think the decision to replace the full screen editor with the distraction free editor was an extremely poor one which did a disservice to your users.
