Customize size and location of panes?

[John Perry]

Is there a way to change the location of the built-in diff view and perhaps to reorder other panes? I'd like the diff view to span the entire bottom of the window. I can drag the divider left but that shrinks the file list. I don't really need the commit details window to show all the time; generally, I can get what I need from checkin comments that appear in the history.

I don't really want to launch an external diff tool for every little change. I just want to customize the built-in panes.

Thanks in advance for your help :-)
