exactly this.

in general it is harder to build tools for graphical languages, I think this has been prohibitive. parser are hard, but diagrams require constraint solvers and what not, on top of the parsing.

but we came a long way since 1990, both on our actual abilities to build the stuff (JS and the browser can do powerful visual things) but we also understand functional programming and it's relation to mathematics much better.

anyway, thanks for your comments! Nice thread and you are 100% right with the TODO list; we actually build a tool (here is a basic pre-version https://github.com/wires/roadmap-viewer) to manage the intricate roadmap needed for this big project. Stay tuned! :-)
