No worries, I said it should work with Tampermonkey, I can at least make sure it actually does. XD

Have updated Greasyfork with a new, slightly-tweaked version of the fix I sent you that should clear up some minor weirdness that can otherwise pop-up on top-level-comment pages >1 (script isn't supposed to run if you're looking at a specific later page, as it doesn't really make sense there) - and should save anyone else installing it from running into the same issue.
