We're all dealing with having to display more complex math to students once you get past 5th grade in the Common Core, also on web and iPads. Appreciate you folks taking the time to release something like this to the public. People haven't been hounding us down because of the slow UX yet, but I can see that happening down the line. I'm hoping we can open source some of our tools as well once we're your size :)
My only other question was: is KaTeX 100% interchangeable with MathJax as far as syntax goes? What I'm asking is if we already have a lot of content written for MathJax, will we need to massage it into a new syntax or should it work for the most part?
