BBEdit's implementation is one horizontal split pane, IIRC. Not good 
enough.

Imagine that you have a really large source file.
Imagine that you need to make changes to code at top of the file that 
require interrelated changes to stuff at the bottom, and/or vice versa.
Imagine these changes are too complicated to hold all of the details in 
your head.

You don't need this often, but when you do, it's essential.

In the past, I've actually used four horizontal split panes working on 
the same document at once. That was a particularly intricate case, but 
I would certainly use the functionality if I had it now. Unfortunately, 
Xcode's pane split UI sucks. MPW did it right (more or less).
