I use the Documentation to find stuff I forget all the time. My first time reading it, I read almost everything (exluding C++, that’s not for me) Now when I forget something or can’t seem to make something work I go back To the Doc. I also use it side by side with the editor. It’s nice to have it there just in case I have as my cousin calls it, A “Brain Fart.”
Also being able to download the vids would be a great addition.
