An updated version of the mathcell concept.
It allows an additional label which can be viewed in edit and results mode which can contain KaTeX.
The cell takes wiki text and my intention is to use with the formula plugin and the KaTeX plugin to make the input of equations a little less cumbersome than the .js equivalent.
Much back and forth with co-pilot, so any feedback welcome and I’ll wrap it up as a plugin.
Cheers
