This is very cool and very much like what I want, but I can see how it's rudimentary. I think the only sustainable approach to these things is to build modular components and keep them separated into different modes/contexts. The advantage of that being that you can easily import symbols/functions from that particular paradigm of math into your notebook and then apply it to what you're doing in order to save time.
