Very nice, but autoplay and "alt" attribute would be nice

This works very nicely, but it means a visitor has to click twice to watch the video (in my case a Vimeo video). It would be better if there was an autoplay option we could use in the shortcode.

My website uses the same lightbox to show images and their “alt” tag value is shown above the lightbox as a title. So would be great if this plugin could also have a “title” attribute.
