If they are looking for paths going forward, I hope they investigate what PopOS is doing with rust (COSMIC) [0] and Iced [1] (cross platform ui library).

I read "A cross-platform GUI library for Rust" but never saw any specifics. Is this targeting MacOS, Windows, Linux?

From [1] https://github.com/iced-rs/iced it says:

"Cross-platform support (Windows, macOS, Linux, and the Web)"
