No way to understand the symbol meaning

### Description

No way to understand why we have a green multiwindow symbol
We are not showing anywhere in the ui(for eg the star icon we have explanation in the tooltip-Please refer image-2)
Also there it shows only one icon if we have this multiwindow and the star icon applicable for particular extension then in that case I think the multiwindow icon takes precedence but to me I feel it's wrong.

@mrleemurray

here in the tooltip we have proper explanation of the icon and what it's for
