Great App to send files or folders to nearby devices or across the ocean. The app is almost perfect without any unlabeled buttons, but for the sake of one or two, which really isn't anything. all you have to do is swipe with two fingers from right to left to switch between Pictures, Text, Apps, Audio, Videos, etc. The other button that doesn't speak, is the "select button" to the right edge of the device across each file of folder name. In other words, when you are in a listview, and you want to selct a particular folder or file to send, there is a "select" button, straight across from the file or folder that you are on, near the right edge of the phone or tablet. I'm contacting him to fix that, but you would have a confirmation as to what was selected and how big it is.
