no support on the first one, i actually quite enjoy shorter pages of only ten posts.
for multi-quoting - no support on pinging (i don’t think it’s that difficult to just add an @, and i think most people prefer not to ping/be pinged when quoting) and i’m not sure on multi-quoting. what would that actually entail? like when you hit quote it auto-adds it to your reply regardless of how many times you’ve already quoted? if that’s what you mean, then i’d support that!
and i’m not really sure what the last one would entail. where would that display exactly?
