edit: if you're using versions 0.38 or 0.39 of this script or last updated/installed it between July 31st, 2023 and August 28th, 2023, there was a security vulnerability that was fixed in version 0.40 (warning post)
I tend to open a lot of tabs and a lot of the time it's to check out the comments of a post
scrolling tabs (motion)

so here's a userscript that lets you see a post's comments without opening it in a new tab

click on the arrow to the left of the comment count to see the comments then click on it again to hide them
reopening the comments refreshes them
tested on both firefox and chrome with tampermonkey and also greasemonkey on firefox
markdown isn't supported (yet?)
any and all suggestions are welcome
edits under the break (last update: 2023-11-23T01:26:45Z, version 0.48)
something like this should be a core feature y'all
comments should just be expandable in place, mobile doesn't play nice with tabs for one thing!
