In 2.79 I could select a workspace, choose any scene and easily switch between workspaces - for example I had one scene for modeling and another one for VSE.
But in 2.8 I can't find a way to do so. It seems like scene selecting is now a global thing and switching between workspaces shares the same scene.
As you can see green highlighted part is a scene created specifically for Video Editing, but if I switched to workspace Layout - I'd still be viewing this scene.
I used to this so much, cause Blender doesn't allow to use same scene as strip in VSE.
