A basic MTP client. Supports MTP devices including those with multiple storage devices (typically mobile phones). Supports Drag'n'Drop interface for upload/download of files. This Doesnt pick up my Device(Droid Ultra) as normal user, so I use gksu to launch it and it works great. Xfsudo works as well. It may or may not detect your device as normal user, I have no idea and I make no promises. This package is built with gtk2 but the default is gtk3, if you would like gtk3, simply delete or comment out the line --with-gtk2 from within the SlackBuild script under the configure flags. There is a FAQ inside the source tarball in the README.
