wagtailmedia has been excellent to use and I'm a huge fan, the only thing I'm yearning for a little bit is the ability to specify attributes. Rather than using gifs, I've been using H264/Webm videos to display animations created with manim. However, the lack of ability to specify loop directly is a minor inconvenience. I figured I'd put this feature request in as it might be helpful to others as well. Thanks for the awesome extension!
