Tweak iOS Binder for Better Outlining

If you made one tweak, the binder would become much more useful as an outliner. For many of us who use longer descriptive titles for documents, we can barely read the titles in the Expanded view of the binder. Any chance on your adding a 3rd option for binder width? Full screen width would be so helpful! (And congratulations again on a very impressive iOS version! Wow!)
