Adding a note to a certain point of the graph

It would also be nice to be able to add comments at certain points, instead of only one big overall comment. Because then I could more easily track/note when I am awake or when something happens.

It would be nice if there were some canned comments to use for this too, so I could just click something once instead of typing. Like, if I wake up in the night, I could click a button that says “woke up” or if I go to the bathroom I could click a button that says “bathroom” or if I have a dream I could click a button that says “bad dream” or “good dream”, ‎"short dream" “long dream” etc.
