I have many folders and files in my main computer's dropbox. I have a laptop with a small SSD so I can't allocate much space for DB. I need to use Selective Sync to pick which folders. By default all folders are checked. It would be very helpful to have a "uncheck all" checkbox in the dialog box, so I only have to check the one folder I want to share. I also want to have a way NOT to sync the files in my root folder.
