idk if PieFed has this, but something Lemmy is missing that Reddit has: modmail. On Reddit you can send a PM that goes to the moderators of the community/subreddit instead of PMing them individually. I actually don't know what it looks like on the moderator's side, I was never a mod for a big subreddit, but I imagine there's a way to prevent every mod from responding to the same message.
My admin panel on Lemmy has a slur regex filter option, and a list of blocked URLs, some options for rate limiting posts/comments/images/PMs/searches/registrations, and a way to view/delete images that were uploaded by users.
One thing I was thinking, I can see the moderation history for a user (all the posts/comments that were deleted and all their bans) but I can't see all of the reports for a user, how many times the user has been reported even with no action taken.
