Ah yes, of course, easy peasy.
I downloaded the luna, changed the graphics, renamed it to diver, changed the xml file to be called diver (including the params inside), but nothing else is changed.
I've uploaded the plugin, but when installed, it doesn't unpack all the files.
Is the luna plugin xml file maybe missing a few lines, it's installed as core element, so I guess it's not installed via the CB plugin mechanism.
The source directory
The resulting directory after installing it via plugin manager.
