Field mapping in GP tools is done through a very small window that is not resizable. This is a real pain when you're reordering and manipulating more than, say, 5-10 fields. As someone who will turn his monitor vertical to get a good look at a table, I would appreciate the ability to make this window larger - perhaps into a separate floating window that I can maximize.

It would also help if I could resize the Output Fields column without making the whole pane wider.
