Immediate mode GUIs are usually pretty inefficient. I wouldn't use it as a permanent solution in a product. More like a quick way to add controls to avoid having to close the app and edit a config file, or recompile with different params. Usually you want app GUIs with a style that matches the rest of the apps. Though mobile kinda changed that. I don't know of a performant UI framework for building non traditional desktop apps.
