Some important things I could focus on next: "remote follow" button on public profiles so poor GS users can easily follow ours (since GS doesn't have a prominent input for doing it otherwise); a report function; list of people you blocked, list of your favourites; allow instance admins to modify homepage description and terms of service dynamically. Not sure which one to pick =.=
@Gargron Personally, a list of favorites is the #1 QoL improvement, though a report feature and a block list are probably more important for the community as a whole.
