Collections are definitely my new favorite thing, and at the moment I believe they're kbin exclusive.
Thanks! Looks like logged out the collection isn't accessible at kbin.social/c/collection-name anymore which is excellent, but is still accessible there when logged in (unexpected, though perhaps only accessible to my account, but I feel bad I might be squatting on a nice collection name) and is also accessible at kbin.social/u/gibandaley/c/collection-name (expected)
Yeah, I favorited my private collection (not sure why I did that...) and it seems to have permanently made it public, no big deal in this case, but I feel bad 'squatting' on collection slug.
Awesome! Multireddit like functionality was what I was missing most, and Categories sounds like it will replace it nicely. Thanks!
I haven't used it, but there's also

Roll20 BlogI finished Psychonauts for the first time a couple of months ago, and just started Psychonauts 2 last night. Only a couple of hours in, but really enjoying it so far.
This is great! That's the only Star Trek related video they have, but there's a bunch of other great 8 bit covers from them:

I mostly make 8-bit arrangements of Pokémon soundtracks (mainly DPPt, HGSS and PMD2) but also Zelda, Mario and occasionally other games, films or “regular” songs. All 8-bit songs are produced in 0CC-FamiTracker and pixel artworks are drawn in Aseprite. Video editing is done using DaVinci Resolve and FFmpeg.

Phanpy, it's a web app (pwa), but you can add to your home screen. In my opinion it handles threads better than any other app I've tried.
