The Unity Editor's handling of multiple windows can be frustrating, especially when wanting to have a tool open on one screen (IE Profiler, Shader Editor, etc), but now *every time you focus on the main editor*. The most simple solution in my eyes: being able to convert a "Unity Window" (tabbed unity windows that is not docked onto the rest of the editor) into a "OS Window", which would create its own tab in the taskbar, and not auto focus when Unity is focused. This would be INCREDIBLY helpful when dealing with complex editor tools in Unity, especially shader editors. And now that Unity is pushing their own Shader Editor, I think this sort of feature is ever more important. If I could implement this myself, I would, but I don't think that's possible.
