> I wish GPUI could become the go-to Rust UI library and not just an editor backend.

In case you find it useful, I recently stumbled upon this project:

https://github.com/longbridge/gpui-component

"UI components for building fantastic desktop applications using GPUI."

I took a look at gpui-component a while ago when assessing GPUI for a project I was working on. IANAL but was dissuaded because it's almost certainly not compliant with the Zed license--gpui-component "borrows" gpui code patterns lifted straight from the main zed repo, which therefore must be AGPL/GPL (unlike the gpui-only which is Apache IIRC). Caveat emptor (caveat user?).
