Make easier for general users.

1. There is an 'activate' button. Rather make it toggle type in the upper part and when the app is started for the first time, it should stay ON.
2. May give three opts: Save(Save changes+Apply+Gets out of settings page), Default(Loads default settings), Cancel(cancels the changes made by the user to the last saved settings).
3. Keep the 'Auto STARTUP' option ON by default.
4. Keep 'All Windows' selected by default in the in/exc app section. Those, who would need it customized, will change it themselves In-shaa-Allaah.
