I'm syncing my entire Dropbox folder with Editorial and it works ok; however, the navigation is not that easy if you have many sub-directories, recent file helps but not always enough.
I realized maybe it would be a good option to either be able to bookmark a folder for faster access. Or, a more advance version of this is to be able to create multiple Dropbox sync folder with different syncing properties like different file type to sync and they all appear in the folder list.
Cheers,
Amir.
