I did some thing,some years ago,maybe useful to you

[langkong]

1,can input latex format for some math,physical,chemical formula
2,can input html link for every node
3,can set an image for every node

and these days ,I add two things
translate node to node by click a button
auto add an image to all node by click another button

Hi @langkong ,

perhaps you can send a link to your version? I will add that to the README file and see if folks want to have these features backported.

Sorry for derailing the thread @ondras
@langkong if possible, could you fork your version?
