What would you want to see in another Twilight Saga book?

I wish there was a book told by some of the supporting characters because I Stephanie Meyers did such a good job creating each character with an interesting background, however the main books are told by Bella. I want to know how the characters think, not just through Edward's loose interpretation but how they go about their day and make choices. I could see a compilation of short stories or a long novel told from 3-4 perspectives that don't focus on Edward and Bella but the other Cullens.
