Wah? WYSIWYG rules the world. Web, mobile, desktop, game dev (The UI the user sees anyway). Anything where visuals matters, WYSIWYG and predefined layouts are used.

IMGUIs are almost always relegated to debug UIs and single devs because its actually terrible to maintain something that binds presentation and business logic like IMGUIs often do (and when they don't they lose the simplicity).
