Seems to not be able to handle all comments, contrary to the description text. Seems to only handle the top level ones. Freezes up on channels with a significant number of comments. Seems to not be able to handle extra replies. i can't use this for what i need, which is all comments, replies, and expanded comments that require the 'see more' to be clicked. Excellent Otherwise. Great for small number of comments.

Saved first 20 comments; addon button on youtube page have strange hitbox.
