It would be nice to have a 'Visibility' checkbox (i.e. Layer 'visibility) added next to the hidden checkbox option that's already in place on this panel.
This would allow for a nice combination of Layer controls without having to go through the extra steps of opening up the Layer Panels just to set the visibility of a layer which I typically already created from within the Entity Info panel in the first place.
I pretty much make all of my new Layers from within the Entity Info panel, since that's also the place where I need to go if I'm assigning an object to a layer anyhow.
So, in that sense having the option to also assign the layers visibility at the same time that I'm creating a new layer name, or simple changing between existing layers, would be a nice convience to have.
