It would be nice if Marknote supported rendering of MathJax (like e.g. Typora does), so that it is possible to read and write mathematical text enclosed in $...$ inside markdown documents. 

This would make it possible for example to use Marknote to take notes in classes on technical subjects.

Possibly https://github.com/nathancarter/qtmathjax could be used for this, though I suppose additional work would be required to split out the MathJax parts from the rest of the markdown which is handed over to QTextDocument.
