There few requirements (in my mind) for proven GUI toolkit (at least on Windows) apart from UX points: - Support multiple windows - Support docking, and dock-in-dock - Deal gracefully with Remote Desktop services If you start with UI toolkit not dealing with any of the above points, you are limited in what you can do. Maybe you don't need the first two, that's fine, this is where electron is. But if you have to do a content creation application (Maya, 3DSMax, Blender, Unreal Editor, etc.) - you need to support multiple windows and docking windows in other windows - preserve layouts, etc. And then Remote Desktop, because you may need someone to assist and log in to the machine, or work remotely (especially today), and if RDP does not work (sorry, but there are some pure OpenGL toolkits), then it's a loss.
