this isn't a suggestion for a priority order, just stuff that's been on my mind lately
- tag filtering
- the ability to mark a post as "unsearchable" (particularly useful once tags have the dual meaning of "a thing to search for" and "a thing to filter out")
- post scheduling (I write my best posts at 2am but I wanna post them when people will see them)
- seeing if a user follows you (I expect this one is kinda controversial because it has Social Implications but I really want to know who my mutuals are and especially who would be my mutual if only I followed them back)
