Nice Idea. But ain't foolproof. Rated 3 out of 5 stars

Its nice to have such a thing. But its not foolproof.

Add Ons: It do lock add ons, but still you can access them by pressing cancel and Esc immediately.
2ndly, it doesn't lock addons at all, in side bar, in case you are using AIOS addon.

This review is for a previous version of the add-on (1.09.1-signed.1-signed).
