I wish I had better news here. Nested collections is another languishing feature suggestion (I’d personally like to see that one). I’m pretty sure that collections based on folders has been suggested as well, but I’m having trouble finding it at the moment.
But collections in their current form cure a lot of library viewing ills, in my opinion. Smart collections in particular provide a great way to automate the creation of collections based on title, director, studio, genre, etc., and can be very useful in creating a library view which is palatable to different users.
