A big challenge is to get references working correctly. LaTeXML is quite good at converting latex documents to html [1], including references such as Theorem 2.

A big challenge is to get references working correctly. LaTeXML is quite good at converting latex documents to html [1], including references such as Theorem 2.1, equation (8.1) etc. For instance, the paper [2] appears to be quite readable on mobile, and clicking/tapping on a reference such as (8.1) leads you to equation (8.1) as you would expect. The auto-generation of Arxiv-Vanity is really nice, maybe it would be easy to add the LatexML output too?
