Not exactly sure what the point of this gui interface is if you have to type in everything but the command. Actually more confusing to try and use this app than just running a command prompt. Example to push pull a file with this this app you need to still know the directory of everything on your phone, which most people won't know how to do. This app wants you to type in /sdcard/download/Filename.file to
to pull a file from your phone. the only thing missing is adb pull
