Lesson text a little too long in some places

[maranr]

I would break up some of the lessons into subpages to avoid scrolling. I found that some sections, like the one on variables, a little long with a number of topics on one page that could be broken up more to keep focus.

Definitely. We're aware of that and plan at least to shorten new lessons (and split them up more). We should then revisit older lessons and do the same where possible.
