silverpill (npub19yg…wysk) are there plans to be able to limit who can post to groups and visibility (group only, instance only, stuff like that) just to have like an internal group for the instance for example. and pinned posts to groups. what do you see groups functioning as, what is your vision? cuz it's just a word groups so i think different people would want to work it differently and i wonder what you want it to be like in mitra and as a FEP or whatever
