Agreed! We haven't brought optimization in-product yet because we want to get it right, but we've been having fun doing things like this more informally. E.g. https://enombic.com/mandelbrot/wsb-MPT uses the markowitz model to calculate its weights.

One of our main goals with enombic is to empower retail investors with more advanced tooling, glad to hear you're sympathetic to this. Would love to chat more about it if you want, hello [at] enombic [dot] com.
