I would like to suggest that the mobile app add functionatliy to better integrate with the DTPO server. While the web interface is useful on my iPad, I would really like to be able to upload and manipulate files. I realize that this would require additional coding on the DTPO side, but I have had some trouble integrating DTTG into my workflow.
For DEVONthink To Go we will enhance the sync interface so that it also supports moving and deleting files (renaming is already possible). And we will extend the web interface to make it much more usable on your local network including the possibility to manipulate files.
