Almost perfect, one suggestion

This plugin is very helpful to download favourite plugins you use on one site to easily implement them on another site. I also made it a habit to download a plugin before updating it, so I can do an easy rollback in case of problems. Having said that, it would be awesome if the downloaded filename would include a version number instead of just the plugin name. That way, you can keep an archive of various versions after updates. The version number for every plugin is displayed in the plugins admin screen, so it should be possible to include this in the filename, right?
