Hey, thanks for sharing. It looks neat! Here's some (unstructured, rushed) feedback:

Consider adding some PWA metadata (manifest) so there's a bit more space when the app is added to the home screen.

Are you using perfect-freehand? If so, you might wanna give Steve Ruiz a shoutout!

The latency is not bad (iOS Safari) to be fair. I'd check how this works with the Apple Pencil though (including the additional APIs and pen properties it opens)

I have giant fingers, so this is nice for doodles, but writing gets frustrating. a basic zoom would fix that (problem: keeping the UI non obtrusive).

Consider adding colour (even a pre-defined palette to keep this super simple, say 3-4 colours). I got some fun creations from people who played with a similar project (https://lines.potato.horse), largely because they had just the right amount of creative control.

Also, consider adding an OLED-friendly colour scheme (with perfect blacks #000). Some inspiration: https://untested.sonnet.io/notes/night-rider/ and https://untested.sonnet.io/notes/dark-mode-articles/

(100% yak shave here, so not important) but: I'd check if the note content could be shared with the link (e.g. via data URIs) (mostly for fun)

Ah, finally, make it plomk like mmm.page or potato.horse (disable silent mode and click on the nav)! THIS IS VERY IMPORTANT

Very cool, though it doesn't seem to work on Firefox on Android - I had to use Chrome to get it to work. Dunno what API it's using, but worth mentioning.

Let's see how this evolves

Can't get it to do anything using Edge on Windows. Does it only work with touch?

Congrats on coming out of the shadows!

If you could increase the size of the drawing window, to be almost as large as the browser and add more basic colors for drawing, I can see it being very useful.

Pretty cool. Though I was a bit sad that preview does not work on Signal.

Have you thought about colour? That would be awesome.

Very few tools write that smooth. Great Work!

very cool and simple idea, i like it. funny thing, first try i got a note-id that already had been used by someone :-)

I really like the feel of the writing.

I’m now able to sign my name with flair using just my thumb while holding my phone—seamlessly and effortlessly. Very well done on the implementation.
