I've updated all the videos and added a lot more detail in the introduction pieces (intro to codegen and intro to qforms, which includes QAjaxAction). Please note that these videos are very rough. There wasn't too much thought or practice done ahead of time, so the length of the videos are a little longer than the previous Beta 1 ones.
Also, we've added a video segment on the more-advance side of things, talking about a full AJAX-based Dashboard for the sample Issue Tracker Pro application.
And finally, the Issue Tracker Pro application has been updated with the Beta 2 code, and we've launched a demo website where you can play with the modified list/edit pages, as well as the new AJAX-based Dashboard.
