Yes, I've learned that Heynote is lacking some documentation. Will improve that.

Math.js (https://mathjs.org/) powers the Math blocks, so what's supported by Math.js should be supported by Heynote, with the addition of currency conversions (exchange rates are updated daily).

> How to convert between fahrenheit and celsius?

This should work:

  10 celsius to fahrenheit

Could it be made to parse "10°C" as "10 celsius" as that is much shorter?

Suggestion: mouse over on green calculated value should show value in multiple formats. E.g. "time = 4000 seconds" could show "01:06:40"

also: "today + 4 days" or "now + 1 day"

Unicode "π" should parse like "PI".

You can do that (and lots more) with Fend: https://github.com/printfn/fend/
