Hello! Can anyone tell what is going on with site design? Why is it constantly changing? Is Jeffrey trying to find the best design or is it some kind of experiment?
For example I find this aquamarine color in menu pretty annoying.
Also I think there is really a bunch of work to do with videos section.
Video block is changing its height 2 times while preloading / starting to play, (it you try to click refs in the bottom of the page during this process, you will probably miss, and I think it annoys users overall). Sliding volume level (with expanding width, pushing video progess bar) is also bad idea. It would be great if volume level would be remembered! Pop up "to continue" should be rethinked, it appears even on videos that were watched to the end. These left and right buttons might not be that useful at all. If mouse pointer is on video they won't disappear.
No offense, I really love what Jeffrey is doing, he is exceptional teacher. But there is a possibility that design should be done in other way.
