Compare two selections (out of scope for the External Tools Plugin, see comments)
I just ran into the situation where I wanted to compare two blocks of code which looked identical.
I created a split view to have those two blocks side by side. I selected both of the blocks (with two views, this is possible).
Now, this is missing: a function that takes both selections and feeds them to kdiff3 (via temp files?).
