Hi All .. we're working on a looper for the video player and posts.  It should be ready in a couple weeks.  You can see our early prototype here

http://1songbook.com/mediaelement/demo/loop.html

You can loop three ways

• click on the A / B  points
• dragging the A / B points
• clicking on a button to loop a certain section (in this case the intro)

The idea is you would be able to click on a button or link next to a riff / chord / tab .. and the video would automatically go to that point and loop it.

Would be great to get your thoughts and feedback.  Thanks.

Mike
