Rated 4 out of 5 stars

I really like this, but I wish it were easier to customize. The options menu has a "services" tab and an "engines" tab, but no apparent way to move these ostensibly available engines into the "services" tab.

Other than that, a brilliant concept. An update just might bring in that 4th star.

This review is for a previous version of the add-on (0.4.2).
