Feature: Hide "Re-scan installed apps" and other buttons while not in apps menu

[NekoJonez]

I don't know if this is a bug or a feature request but I think it would be neat if the two buttons of "Re-scan installed apps" and the button you click to let the program start updating programs disappear in the options, uninstaller, scheduler and about menu. Since they serve no purpose there and they cause a minor visual bug since the program jumps to the apps section without showing that on the menu at the left hand side.
