Just a review tip, you can write comments in the comment box under the move tree and it stays attached to move.
It also highlights the move in the move tree blue so you can see which moves have comments.
You can see lots of examples for instance in this series of lectures Becoming 9 Kyu - A Series for Beginners, mark5000 does full lectures using the comments in the tree for his thoughts, and uses the chat for discussion with whoever’s watching.
Here’s a direct link to the first lecture/review board to give you an (a visual) idea
