That's largely my concern with Dear ImGui et al. It's okay to have it as a debug environment in a game, it's not okay to have it as an application. The lead developer agrees: "I do know that Dear ImGui unfortunately does not align with requirements of accessible software. It was designed as a technical/debug tooling software to be used as an overlay over 3d/graphics applications which themselves tends to have little to no accessibility features. It's not really my fault that people have started using it for desktop-ey applications." (GH issue 7892)
The one thing I don’t like about it is that you can’t really get the apps to look “native” in any shape or form, and that you have to roll your own widgets for a few things (which is why I went back to some of the wxWidgets stuff I have listed in https://taoofmac.com/space/dev/native)
I hope you find it useful!
that would make it would be an excellent option for desktop app development.
