Better visual interface for RenderLayers and their Collections

I know that there is still a lot going on with development, but I really do not like the way Blender currently shows the RenderLayers and their Collections.
That’s why I created this simple mockup of an interface for RenderLayers that is based on the old system but now uses collections.
The user is now able to add his collections to the belonging layer. There is also an icon to set a collection as Mask-Collection for example.


Yes, I thought of very similar idea, but inside outliner. What do you think?



Also a very nice idea.
But to be honest. I would much more prefer a seperate menu like I posted it above.
Maybe both is possible?
