Back before kbin fell off the internet it had a really neat experimental “collections” feature that would let you make named groups of communities. Collections could be used either privately or made public so other people could subscribe to your curated feed on a topic. The owner could update the collection as needed (e.g. adding or removing communities/magazines as they changed over time).

It’s one of the kbin features I miss most on lemmy.

Does anyone know if mbin ever got a copy of that? I know they forked off before it was added to kbin, but I don’t know if it ever got integrated later. (I don’t see it from a quick glance at moist and fedia, but I haven’t dug into the dev history.)
