KaTeX plugin: predefined LaTeX macros

[Szabolcs Horvát]

Hello everyone,

I am returning to Tiddlywiki after many years and many things are different.  I need math support and the KaTeX plugin works well.

But I was wondering if there is a way to define LaTeX commands which I can use in any KaTeX block.  Is this possible?  If yes, is it possible within the scope of a whole wiki?  Within the scope of a tiddler?

Does the KaTeX plugin have some sort of official status that the MathJax plugin doesn't have?  Is the KaTeX plugin likely more future proof because of this?  MathJax is much more capable than KaTeX, but I strongly prefer reliability.
