Two Scenes Window in the Editor (hide UI) hide layer just for one

Hello,

you know you have top right layers to lock or hide some layers for example UI. I wanted to add to scene windows to have one for just UI and one for entire map/scene because its sometimes annoying to see UI but still working with both at sime time.
So the trick with layers do not work because it hides on both scenes.

Do you guys have another idea to make this real?
