Following a video tutorial "hands on," requires very frequent pausing of the YouTube video stream.
When the video is paused, it displays a status bar which obscures the lowest part of the video.
In a few of the getting-started videos, a number of style entries were made at the very bottom of the screen.
I had to rewind a portion of the video (after pausing it) very frequently to be able to see the lowest part of the video image.
This problem could be avoided if the lowest part of the video's image does not contain any information that is important at that moment.
Thank you for raising that issue. I'm sorry it caused problems for following the videos. I'll bear it in mind if Adobe asks me to update the videos or create new ones.
