Currently "Options" is a tab in the DZPro UI.
This makes the behavior of this dialog pretty weird - making the buttons at the bottom change.
Seems like it would be simpler, and make a lot more sense in the UI for options to be a separate dialog.
Instead of "Files" "Options" tabs, make "Options" be a button.
(Oh, and put the Options button in the side-by-side diff window too!).
Then you could also allow for saved options sets - much like the new "Match color" options thing in the Find dialog.
