Describe the incorrect/future/missing documentation

After transitioning to Sphinx-based documentation, we've lost formatting of function signatures along with the majority of syntax highlighting. This makes reading reference documentation an actual challenge:

We should investigate if there's any way to a) format function signatures to at least get each parameter on a new line, b) return syntax highlighting.

If this is a correction, please provide a link to the incorrect documentation. If this is a new documentation request, please link to where you have looked.
