Thanks. That's what I expected to see, but I don't.
In Items To Show when I click Add I get choice of "Library View" or "Library View From Standard View" but I never get option to add a field like Genre.
And on the right side, I never see the box below View Name with the Add/Edit/Remove options.
Don't know if this has something to do with it but I have customized Audio/Images/Video views to be All/Music/Movies and have overidden default media types for each.
Something is clearly wrong on my system or else I am stupid.
Try this:
1) On the left, pick Add > Library View
2) On the left, pick Add > Library View
3) Ensure that the second view is nested under the first view (use the "Nest" button if necessary)
4) Select the second, nested view
5) On the right, pick Add...
6) You should see a dialog listing components like Genre, Artist, etc.
Remember that root views (views that are not nested) are different and do not have components on the right.
It's very possible there's a bug so I'm just trying to understand what might be different.
