Auto import

The auto import feature is very handy however there are some times where it gets in the way.

One problem I have is with undos. If I paste some code and that code has some imports added then I try an undo back to the point before I pasted the code it keeps reimporting again. I'm thinking autoimport should be temporarily suspended when the user invokes the undo command. Either that or there needs to be a very easy and quick way to turn autoimport off.
