I have been thinking about an extension module to configure MathJax. It would use json_econde() so, if this gets implemented the mod will only support php > 5.2 or even 5.3 if I really need that options parameter (for reference phpbb-develop requires 5.2).
I still didn't look at how to store the configuration. A whole database table yes, but how am I going to layout the different values since they can contain other objects/arrays?
I'm using raw.github.com to serve the file directly from the master repo, so the problem might be that github is forcing an HTTPS connection and the mod can't handle it.
First of all thx for Your effort!
Secondly where do I find file responsible for configuration? I'd like to change rendered text font size. Style settings in mod's tab in admin's panel would be a great fature : )
Configuration should be done on install preferably on UMIL if it supports user input.
This implies some work to "port" parts of the acp module to UMIL and making sure theres no conflicts. Depending on how complex it becomes it might need UMIL's manual method.
