Atleast on chrome win7 the font is absolutely awful.
Could you post a screenshot? I mostly just use the default "sans" which can result in any font being used based on the OS,
Also any chance that it could output json to represent modules instead of html?
Very unlikely in near future, I've refactored *most* HTML writing code but the rest would still need a lot of work, and then there'd be a non-trivial chunk of "HTMLWriter" code to rewrite (1k lines), which would likely result in finding finding more deficencies in separation of HTML writing from the rest of the code.
