The thing I'd most like more of is fic that really engages with canon, both the magical world and the political themes. There seems to be a lot of mundane AUs these days, and although they can be good frothy and fluffy fun, there seems to be a tendency to rely on popular fanon rather than drawing much on canon. There are still fics doing it - quite a few of the stories from these year's RS Games had interesting things to say on everything from magic to the rise of fascism - but I always want more.

There's been some real improvements in the politics of fandom (I can't think of a better way of describing it!) Less misogyny, fewer weirdly homophobic tropes - there are people in fandom today who don't even know what WNGWJLEO* means and that makes me so happy! Characters no longer assumed to be white unless proven otherwise, although unfortunately I'm still seeing some pretty unpleasant pushback against that, especially towards fanartists.
