Cloud profiles - back up + access your layout/settings across multiple devices
Cloud (Google+/Facebook sign in?) back up that stores your app layout and settings via online profile(s) that can be accessed by other handsets given permission of creator. Layout/setting profile shareing could happen amongst local friend's (via Bluetooth/wifi direct), online friends via social media connections, and a possible online forum hosted/managed by yourselves.
I attempted to access a back up file via another device of mine but it did not work even with me manually transferring the file. This service would benefit new users introduced to the app by friends to using it quicker and prevent existing users having to manually recreate their set up on newer handsets.
