@Claire biggest one for me is probably better APIs for admin features, having to hack around with the endpoints that the GUI calls is a bit rough, and it would be nice to automate among other things:
* announcements
* federation (listing/creating/removing/updating)
* invites (listing/creating/removing)
* blocked email domains (listing/creating/removing)
other than that, having emojos be an admin thing instead of a mod thing has always baffled me
