When I change the Function keys in Options+ for a specific application, there's no indicator that the key has been customized/changed. So if I have 10 different applications with individual settings for the Function keys, I have to go through all of them for each application, i.e. 17*10 to see if I've changed it or not.
Intuitively I'd like to see e.g. white borders (as-is) for unchanged keys, and e.g. the logitech green borders for key that have been changed/customized.
