Thank you!
Sure, I can ask. But look, you answered 10 hours later. Do you think I sit still that time? Also before I ask I look through other questions etc. This breaks the tutorial flow.
A issue I will always remember is the shortcut for “Recalculate Normals” with CTRL+N. But the shortcut is SHIFT+N. (CTRL+N is new File) And this is even wrong in the official documentation Normals — Blender Manual :

You are right, that to take the tutorials offline is exaggerated. Hints or subtitles would be great. I think leave them the way they are is wrong.
And you are right the principles are still valid. But principles that can not be applied have not much value. I joined here because I want high quality tutorials. My honest opinion is that this does not met my expectations.
