Hi. Great plugin that worked out of the box for me. Thanks!
I'm wondering whether you can expand the plugin's capabilities. In order of importance to me:
1) Add width and height for the audio player.
2) Allow for a player in a widget (width would be important here).
3) Allow a form of the shortcode which takes a post enclosure URL as the source URL. e.g. [audio src="field:enclosure"] (for flexibility) or just [audio enclosure].
