I really like this approach, and think it should be used more!
In a previous experiment, I created a simple webpage which renders media stored in the URL. This way, it's able to store and render images, audio, and even simple webpages and games. URLs can get quite long, so can store quite a bit of data.
If I read [1] correctly, it seems it checks against lockfile, not pyproject.toml. So it seems like it won't help if I change pyproject.toml manually. Which is a big inconveniece, if so.
Whatever, I think I'll try it for myself later today. It's long overdue.
I created https://floatynotes.app a while ago, which might fit your list :). It provides virtual sticky notes, using the new Document Picture-in-Picture API.
