It's a bit unfortunate that the 'pimped' gorilla effort was focused on just reimplementing it - with total backward capability. Even so, the fact that this variant is based on Reagent (maybe even re-frame) would be a great place to maybe start. Pulling in and using gyptis to replace the plotting would be another step forward as it would be a more solid starting point for plotting (and still uses vega) (gyptis is stagnant, but already has a lot of dynamic aspects to the plots).

Definitely still use gorilla's renderer - that will also keep the useful plugins for it.

The big step would be to make the editor a 'real' editor - protorepl would be the place to look for that as it should be runnable in the browser.

I readily realize that all of this would require serious effort to make it 'real' - not just a kinda sorta works proof of concept.

what you say makes sense though, so we might at least check how much effort that would cost
