a. This adds unwanted Browser chrome/boilerplate.
b. Doesn't work in standalone app.

A nice solution might be to save as PDF using html2pdf. But that adds almost a megabyte of JS code. The whole system is around 3Mb, so this is pretty high overhead. We could load it lazily, which means it only works when we're online. Not very attractive either.
