We use "dear imgui" for fast prototyping, some of those prototypes got to be production software. At first we were worried about the screen always updating and consuming so much energy, but reading the code it became obvious that it was extremely simple to fork the imgui with a very small update screen change, so it only updates when we do something. Imguis and game engines are much simpler to code than conventional GUI because you don't need to handle so much state.
