Reset and Full Reset on exit

This feature that I’m requesting can be found on QtWeb a browser built-on Privacy and Portability, it can be found under Privacy when you start-up the browser. On QtWeb the feature Reset can reset minor things (like emptying the Cache, deleting cookies, fixing the toolbar, resetting the settings) and so on, but the main thing I like is Full Reset that can reset all minor things and also all major things (stuff that the browser creates after its installed) like registry files/entries, this makes the browser very portable. So the thing that I want is to be able to reset things like me messing with the toolbar but can’t fix it or messing with the setting and can’t remember how to fix it, and even better to be able to reset everything back to the way it was like it was never installed, to me this would make this browser very portable and that’s it for this request, thanks for noticing.
