@rysiek@coldredlight@peyotecosmico from my experience modding on Facebook, the things I most often wished for were just better views of incoming comments. Being able to sort and group by time on a certain post, for example, and then filter that list by keyword so I can take bulk actions.
Being able to restrict who can comment on a post helps a LOT. The amount of harassment I had to deal with dropped significantly when I could change a post to only accounts over a certain age, for example.
