Hi I installed via greasemonkey and it took me a while of switching on/off to discern a ny difference.
All I can see is that for thread pages, top level comments, at the bottom, there is a link toggle replies (x) (x = # of replies) which hides comments below.
I disabled any other plugin/userstyle/userscript that might be acting on lemmy/kbin.
If you check the sidebar settings you can see a list of stuff that you can toggle with kbin enhancement script. Things such as showing the host instance for a user/magazine, moving the comment box to the top of comments, letting you collapse comment threads, showing the OP in a thread, etc. it does a lot of the things I felt kbin was lacking.
