Nice - I'll give it props for: > 1 metre + 8 chain = 161.9344 m > 1 tonne + 1 short ton = 1.90718474 t > 1 tonne + 1 long ton = 2.0160469 t and give it a pass for not supporting pre 1963 UK | US historic weights and measures .. that's getting into a pretty specific use case where Standards nerds like to have a clear display of what conversion factors are in play and what provenance those factors have. Time Zone suppo…

Well, I love this comment. And yes, time zone support terrifies me an order of magnitude more than anything else on the list.

On the gnarly scale dealing with with pre-WGS84 paper maps from about the globe is arguably worse ..

there are so many reference ellipsoids and datums used in different parts of the world at different times .. and then there are the many variations on curved surface to flat map projections to deal with.

But yes - Time and date is an iceberg domain :-)

You're right, I'm using lz-string to compress the text before shoving it in the URL. This is definitely a necessary evil for the time being so I don't need a back end component to the app. But eventually I do want prettier URLs and collaborative editing if I can make that work without it bankrupting me or driving me insane.

This looks pretty cool. I've long been looking for something similar to Soulver (https://soulver.app/) that I can use on Linux. This seems promising.

One small criticism: In my opinion, no web-based writing app is useful unless the tab key inserts a tab. The default behavior of most browsers to move focus to the next field is tremendously infuriating in this context. Unfortunately, that's what happens here, at least for Firefox.

(Related: key combinations that normally perform cursor movements but which are often used by browser for navigation.)

TIL that it is convention in the English language to place the euro sign in front of the amount and not after it, like in most other European languages.

TIL: Germans put it after the amount :-)

(I'm European too and I thought it was always in front, everywhere)
