Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

WebGPU Fundamentals
This is true, but there is a lot more to the story. For one, WebGPU does not (yet) support mesh shaders, though it may later as an extension. For two, consider a glyph such as "o" that has two contours. Real triangulation generates a mesh that only generates triangles between the outer and inner contours, and mesh shaders aren't good at that. There are techniques (cover and stencil) that draw twice, incrementing and decrementing a winding number stored in the stencil buffer (see contrast renderer[1] for a clean modern implementation), but it does require nontrivial tracking on the CPU side, and can result in lots of draw calls to switch between the cover and stencil stages unless sophisticated batching is done.
Compute shaders avoid all these problems and work on WebGPU 1.0 today.

Rust: State of GUI, December 2022 – KAS blog
Thanks!
You can also checkout the "feature/ui" branch in GIT [1] to get the UI framework prototype.

Writing Gnome Apps with Swift
There is Relm (https://relm4.org/). Which is in Rust is just GTK (through it's Rust bindings) with a nice reactivity layer on top.

Resources for learning to write ui files for GTK4
I’d recommend you checking out https://relm4.org if you know a little Rust. Relm4 is currently the easiest and most intuitive way to write GTK

[media] Czkawka 6.0 - File cleaner, now finds similar audio files by content, files by size and name and fix and speedup similar images search
Relm4 might make your migration easier. It has factories which make it easy to create lists (both sync and async) and recently added TypedListView as another useful abstraction over pure gtk-rs. There is a lot of potential in Rust + GTK, you just have to find idiomatic abstractions.

What are the scenarios where "Rewrite it in Rust" didn't meet your expectations or couldn't be successfully implemented?
Did you try Relm? It's an implementation is the elm architecture (think react) on top of Gtk. Given your experience with Gtk it might suit you really well, as you can even take only parts of it and continue using bare Gtk for the rest. Give it a try!

GUI development with Rust and GTK 4
What about relm4? Is it generally feature complete? Can one use relm4 for most things, and drop to gtk4 for the oddball task that is not supported?

Forte! A new way of writing Gtk apps for GNOME.
What advantage would this Rust crate have over Relm4? It seems pretty similar to me, save for the property based syntax that Forte has, instead of the set_* ones used on Relm4.

Need guidance for developping GTK4 + Libwaita apps
If you like Rust I recommend Relm4, one of the best experiences I’ve had with a framework tbh, be sure to learn gtk-rs first.
