I just downloaded and installed and I am really impressed. I liked the concept of math blocks though it took me a few seconds to figure out how to change a new block into a math block. This note at the top wasn't clear to me:

⌘ + L Change block language

The phrase block language didn't trigger my "change the type of block" thinking. I might slightly rephrase like:

⌘ + L Change block language (Math, Markdown, etc.)

Otherwise, I think this is a great "scratches an itch" type project. Congrats!

Good suggestion, I'll change that!

"Change block type" makes more sense then "Change block language". "Language" sounds like it could mean English, French, etc. whereas "block type" is unambiguous.

All blocks should be collapsable - I was playing with it and had to enter a comment marker in some to be able to get the collapse arrow in the bar, like # in a python block, however the behavior for a python block collapsing vs another - is that the python block collapses to ' ... ' Whereas, other blocks maintain the firt row as a header, so if I label another block NOTES and collapse it, I can still see the header.

So a collapse button on every block would be nice.

I love this. Thank you.

I agree! This would (will hopefully) be an improvement.

Maybe a block header which includes the timestamp for block birth and whatever text on that line for the title. So row 0 of every block would be the block meta header? no feature creep I promise...

Oh! and one more thing....

It would be nice with some documentation of what the Math mode supports, e.g. syntax, units, functions.

It can be difficult to figure out why some lines are interpreted ok and while others fail.

How to convert between fahrenheit and celsius?

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/
