Bit of a nightmare getting this elegant enough on a phone, and doubt anyone wants to draw ASCII digrams on their phone anyway, so not really a priority!
It really depends how much demand there is. It's a great next step but a lot of work - I was thinking about training a neural net to parse images / 3rd party diagrams into Cascii, but right now I need a break from my screen for a few weeks :)
Yeah I'd like to talk about going back to basics with single-HTML / vanilla JS. It was a great experience, though admittedly controversial and I was expecting more people to be anti it.
