Hello! It came to mind today that it might be interesting to allow for a short delay between the moment a file is added and the moment it starts synchronizing with the servers. I often find myself, for example, unzipping a complete archive into a folder but only wanting to access part of the contents, so I delete the unwanted files but dropbox has already started trying to sync them. It would help to avoid a certain amount of unnecessary network transactions. Perhaps the gain would be negligible though.
