Yes, Cursive does use some renderers internally, and it could probably do with more. If there are types that you’d like to see presented differently, I’m interested to know about them. I’d have to check the vector case though, I usually see them presented as lists.

To be honest nice ways of showing more complex stuff in ways that can be expanded, using nav and datify would be cool. I've never really used REBL that much, but if it was to a degree available in cursive that would be amazing...

I’m actually planning that soon, with inline rendering.
