I like it, seems mostly unobtrusive, add exception list if possible Rated 4 out of 5 stars

It's been working well for me for a couple months. Generally it just works and I don't pay much attention. I add my vote for adding a user-customizable exception list if it doesn't interfere with the developer's intent for a lightweight extension.

This review is for a previous version of the add-on (2.0.1-signed).
