This userscript for kbin enhances the comment section adjusting the layout and adding a line to the left of each comment and its replies that lets you collapse them.

If you don’t have a userscript manager extension installed, you can install Tampermonkey, and then open the greasyfork link above.
Great idea, but the main issue with that is that it isn’t compatible with mobile Safari. I’ll figure out some way to make it clearer
