I also dont see much use for an app like this but if you are interested in hearing any suggestions on how to improve it, here are mine:

- UI Elements should have a functional layout, not just being scattered around the window.
- Group buttons according to the their function, maybe using a tabbed interface or something similar.
- If you want this to be useful to newbies, all functions could be explained in detail on what they do and change, same as you did with the SetFile and Show Drives in TM options.
