Make coloured project area transparent, especially on satellite view

[cmy]

I find the yellow “geographical area” overlay in a project makes it difficult to read the map underneath, especially with satellite view – would it be possible to have only the outer edge, or a layer option?
This is how a Project area looks

and the same area on the “Explore” view

I like that the shading clearly shows what’s in and what’s out. If it were easy to implement, a toggle to turn on and off that shading would be cool… But maybe default it to on and just toggle it off when need to see the detail…
