Hide pdf source but keep AI tutor/summery

most of the time when i write notes from the source i barely look at the actual lesson and just focus on the summery because its quicker and easier (it was an amazing addition btw thank you). but when i try to keep the summery but hide the document it doesnt let me, they just stay together and it looks like so much is going on at the same time.

even when i try to minimise the pdf as much as i can its presense anoys me so much lol. if there could be maybe an extra (-) sign at the top of the pdf that allows us to remove the pdf but not the summery and ai tutor that would be great👀👀

it just looks alot cleaner without the pdf🥲🥲. sorry for the long post and thank youu.
