I was quite surprised by 2 factors that I encountered: 1. The videos do not have subtitles or captions. Yes, the content of the class is downloadable in a pdf format and the lecturers speak slowly and clearly, however, it is a feature that is very well spread in any video format and it would be very helpful as the classes are recommended for not native english speakers as well. 2. If I interrupt a video, and go back later to that one, it does not keep the point where I last interrupted, which is also a very common and wide spread feature and I would expect it. Another thing: 3. The texts on the lectures of Andy McIndoe contain a lot of mispelling in the plants' latin name. There are not many texts so I would assume it is not difficult to write them down correctly and also, check them for spelling.
