Thanks for taking the time to reply. I am 100% in support of software like this being open-source. Not just because companies go out of business and disappear, but for scientific-computing software, it's important to be able to extend these systems. When I talk about features, I often mean can I rewrite this integral into something more computationally tractable? Or is there some reparameterization of this function into something differentiable? I know this are very much how someone might pose a problem coming from Mathematica or Maple, but really I hope it's clear the end goal is still the same. Discover an equivalent mathematical representation of my problem that's more amendable for further work.
