1. Add more practice. As a person, who learns by doing things (I have bad perception by listening or watching) it is crucial for me to have more practice. Otherwise, I would have to do some practice on my own, which would cost me extra time and money. I suppose, now I need to find some simulator on analyzing company's data and make my own conclusions. 2. Try to widen the range of examples: online services, medical centers, recreational institutions etc. 3. I want double mouse click to expand video. And I want space to pause/play the video. Just as on youtube. Now Space triggers the last clicked button on the videoplayer. So, sometimes I click Space and video simply quits fullscreen. 4. I want the autoplay function to play videos right away and open them in full screen (or in the same view, as the previous one was). Now, after the previous video is finished, I get simply redirected to the next one, which does not start. 5. I want the "Next" button somewhere in the video player, so I could proceed to the following video without waiting for the current one to end. Searching in the right panel is not convenient.
