The next priority for the core team is getting feedback on this: Backups to Google Drive from Central will stop working after Jan 31st. I'm particular, we'd like to understand who should be responsible for backups.

And if we have time, I can show a quick demo of some of the visual changes that are coming to ODK docs.
