There are two improvements I imagine useful for the Sync functionality:
  1. Sync port status: at the moment, on the device there is no way to see if the Sync port is open (Sync has been activated in the main menu), and whether the device is actually being synced
  2. Possibility to close the Sync port: IMHO it should be possible to close the Sync port. This is more of a security issue, I see some danger in leaving the Sync port open after synching, especially as it is almost impossible to keep the devices from connecting when and where they want...

This said, I want you to know, that I like DejyOffice very much. It has been the trigger for my switch from my Palm to an Android tablet, and I have not been disappointed!
