Medieval hats as accessories. (Anybody who knows me knew something like that was coming.) Medieval men's hats, either as accessories or as hairs (some wouldn't work as accessories; they're too close to the head.) I will find you pictures.

Pregnant morphs on TF clothes, especially period meshes. Because somebody who wants to play a clueless teen hobag would be perfectly content with unbuttoned Daisy Dukes painted on the nude mesh, but there's a certain portion of the population where... *makes up names* Lady Miranda of Stonebridge is married, expecting her second child, and all of fifteen. (And even for the clueless teen hobags, there should be some nice long dress morphs-- otherwise, how's she going to have that baby in the girls' room at prom? ... Which totally sounds like something a Sim would do anyway...) Also, pregnant morphs on period menswear. Really, though, there are just never enough pregmorphs-- not even for AF.

And hey, here's a nice general one-- Really good seamless wooden floors, with planks and no pegs or nails showing, in heaps of colors. I have SO MANY floors, but I only ever seem to use a few of them... because all the ones with the good seamless textures have never-ending planks.

I'll stop there, because there are lots of generalized things I wish there were more of.
