The Dear ImGui readme is a good starting point:
https://github.com/ocornut/imgui
...now of course Dear ImGui is a specific implementation of an immediate mode UI framework, but it's also the most popular implementation.
I cannot recommend immediate mode GUI programming based on the limitations I've experienced working with egui.
egui does not support putting two widgets in the center of the screen: https://github.com/emilk/egui/issues/3211
It's really easy to get started with immediate mode, it's really easy to bust out some UI, but the second you start trying to involve dynamically resized context and responsive layouts -- abandon all hope. The fact it has to calculate everything in a single pass makes these things hard/impossible.
... that said, I'm still using it for https://ant.care/ (https://github.com/MeoMix/symbiants) because it's the best thing I've found. I'm crossing my fingers that Bevy's UI story (or Kayak https://github.com/StarArawn/kayak_ui) become significantly more fleshed out sooner rather than later. Bevy 0.13 should have lots more in this area though (https://github.com/bevyengine/bevy/discussions/9538)

There is also microui, which I like[0].
Which I forked to work with SDL2[1], no guarantees. It's fun to hack on.

I haven't. I was just searching for a GUI library that was Bevy-compatible and slint isn't at the moment: https://github.com/slint-ui/slint/discussions/940
Sorry!
otherwise, if we have only retained mode as in browsers, we will need to modify the DOM heavily and create temporary elements for handles.

The RemedyBG debugger (https://remedybg.handmade.network/) and the Tracy profiler (https://github.com/wolfpld/tracy) both use Dear ImGui and so far I've only read high praise from people who used those tools compared to the 'established' alternatives.
For tools like this, programmers are also just "normal users", and from the developer side, I'm sure they evaluated various alternatives with all their pros and cons before settling for Dear ImGui.

I've had to spend a lot of time improving egui and it's ecosystem in the process of building my app but it seems to be worth it.
If you're not building a graphical app it probably makes more sense to use something like tauri or flutter as the gui to build a cross platform app with rust, at least until it's gui ecosystem matures.
I didn't use RemedyBG or Tracy, but I did try ImHex (https://github.com/WerWolv/ImHex) and it loaded 12% of the CPU because everything is being repainted 60 times per second. Heck, it even has an option to limit the FPS, which solves the CPU load a bit, but at the same time results in sluggish input because the event handling is tied to the drawing frequency.
So yes, the experience was not good, and I don't see what these tools would lose by using a proper GUI. I don't want every utility to drain my laptop battery like a decent video game.
ImGui is great if you already have a loop where everything is unconditionally redrawn every frame, but otherwise it's a really odd choice for an end-user application.
