I’ve been keeping an eye on the various UI libraries when they come up: right now it seems to take me around a month to add a new one so I’m waiting for one to get traction.

Something else that’s a problem is that as a drawing app, FlowBetween wants to be able to get access to data from a digitizer: pen pressure and tilt in particular. A lot of UI libraries don’t think to pass that through from the operating system, or have an awkward API (browser support is also very spotty for this)

I like to draw, and I suppose my frustrations with other animation packages that I’ve tried were the main inspiration. It’s quite nice to have something that combines two hobbies into one.

When I started I picked Rust because I’d been learning it and wanted to try using it on a more substantial project. I’m very happy with it as a choice of language: it definitely has a difficult learning curve especially with the way borrowing looks similar to references in a garbage-collected languages but works very differently. However, it’s a very expressive language: something about it makes it very easy to write code quickly that’s still very easy to follow later on.
