It was essentially MacPaint with a few controls and a scripting language. While fundamentally it was persistent cards with fields, buttons, and actions, as presented with the assorted demos, it was graphically rich.
And myself, I am not graphically rich. Hardly. I find it intimidating. I find the web intimidating for the same reason. I really struggle trying to make a web page, even with a zillion templates. For whatever reason, it’s very hard for me.
It’s a cool system. It was a bit hamstrung later on by being trapped with its original card size. Even as screens got larger.
