Well, some way or the other, I managed to make the SN mobile friendly-ish, it's now useable at least. The auto-adjusting font-size is pretty maddening though when on mobile. The rem unit is supposed to make the font-size relative to the root font-size, so why is some texts are still changing and appears smaller than the rest?
As it turns out, there's an exception and I have to explicitly set `text-size-adjust: none` to disable this behaviour. Some say this isn't a CSS best practice, but screw that.
This early afternoon, I also made some changes in the backend, fixed and simplified some problematic code that's causing race conditions. I also added an option to cache loaded lua modules, to speed things a little.
Played around with the notebook, I could more or less get apply the division rule with power rule and product rule. Or really, I only ever need sum rule and product rule. But I can see why there are separate rules for each, since it's not always trivial or obvious, even a bit tedious, to get the directive directly from just the sum and product rule.
But, I'm still not comfortable with the syntax. When it says differential of a dependent variable, it's talking about differential of a function, right? Then, it goes around adding functions together, which is essentially a type error. Likely, it's implied and goes without saying that it's the result of the function that's being added together, not the function themselves.
Nope, my entire being rejects this convention. Where's the fully typed math syntax, I want it.
