Work to work relationships

I'm engaged in the task of updating work to work relationships in my library. As a result, I feel the interface could use improvement:

1. The ability to reorder existing relationships. Often I find anthologies have the components in different orderings, and it's extremely difficult to work out which relationship is missing. I appreciate the print edition and an ebook edition may have changed the order; that can't be helped - perhaps the display can be alphabetic? It's only in the interface this would be useful.

2. The ability to dismiss all relationships. If we get (1), this isn't as necessary; but if (1) isn't possible, sometimes clearing everything out and starting over is the best way to go.

3. In the search results, displaying the number of members. It's helpful to see the 0-copies.

Can we also add a way to sort the search results? Maybe by title?

A really sparkly pony would be to show why a result is displaying from your search terms, but that would mean some kind of advanced search...
