Rated 4 out of 5 stars
With the addition of the features listed above, this would be, unquestionably, the definitive userstyle add-on. Unfortunately, it appears development has ceased. Too bad.This review is for a previous version of the add-on (1.0.1-signed).
It has not ceased, just stalled. I am just too much occupied in other important stuff. I am a single person, I have to prioritize things.
