On a small tangent, I've been working on a different Sage rework concept lately that I'm feeling really happy with if anyone wants to take a look at this document. I'm trying to add as much information as possible to what's different and what the logic is behind certain things with highlighting and footnotes, so I hope it's nice and readable. May turn sharing off in the future if I go back and play with things some more, but I think there's a lot of promise in something like this.
