Dropbox just released a beta update that improves the UI and some other features of the app. Their platform of choice for the beta update was the Nexus 7. Here's a brief summary of the changes:
  • better video playback
  • UI improvements
  • app compatibility with direct presentation of files - (basically this is if you click on a file in Dropbox, the corresponding handler app on your device will open.)

There were also some bug fixes that are included in this new update. You can find out more at the Dropbox source link below.
