This is not content related rather functionality related. In the browser, it would be helpful to have a “cinema” mode" like many other tutorial/learning websites. Currently, only fullscreen mode is available which does not help if one has a widescreen monitor and would like to watch tutorials on one part of the screen and have the engine running in the other half. Also, watching the movies on an ipad is very challenging as they do not properly resize and it is a hassle to get to the “fullscreen” button at the bottom right-hand corner of the window.
