This is great but I feel like the potential is underused.

I know its a lot of work but I think we all could desperately use an interactive LaTeX notebook instead of limiting it to only the PDF backend and this work helps a lot with achieving that endeavour. Though it'll be limited to LuaTeX, it'll still be quite something.

Back in the 90's, one of my professors had such software on Solaris.

The experience was just like using Word, but with LaTeX.

Unfortunately not the kind of stuff the vi and emacs folks care about.

Although LyX comes close.
