Switch editors button for viewport local windows

Hello guys. I would like to propose a feature that would allow the user to switch between two editors that has been set by the user. I have post a few mockups of this function recently and this might be the final version of it.

The whole idea of this is just to have some ability to switch between editors without the use of hotkeys. Hotkeys can also be quite useful but In my opinion this is much faster than removing your hands from the keyboard and mouse. Hovering the mouse into a button can be a much faster way of switching between nodes with the help of a tab system.

Although I cannot confirm that this proposal is the best way to implement the tab system within the viewport's local windows, the main purpose of this post is just to create a conversation of how it can be a useful function for blender to look into in the near future.

Thanks.
