Readmees

On both rich and textual, there's a feature in their readmees of these drop downs. So you can, you can open up a section that maybe like, uh, the rich library talking about different ones. It would be kind of overwhelming to have the whole thing listed here, but having him collapsed is kind of a neat idea with little things. I'd be curious actually to see how that might carry over to like pi, pi.org or something like that.
