You’re on Lemmy, so everyone and their mother is going to scream “Why are you using Reddit?!”
Instead, I’ll scream “Why are you using New Reddit?!”
New Reddit, along with generally sucking ass, hates automatically expanding comments. Old Reddit less so.
Hell, I’d wager a chunk of those Userscripts are for old Reddit, too.
Change any www.reddit.com
url to old.reddit.com
and enjoy the old non-sucky UI, complete with comment threads that aren’t automatically collapsed after one reply.
You can make Reddit automatically change to the old design via a user script, extension, or account setting. I’ll leave that exercise for the reader, though.
Enjoy browsing through support threads easier!
Use RES, it has built-in dark mode support in its many, many settings. Highly recommend.
