By default, inserting a cell sticks it at the bottom of the page. However, I'd like to keep my notes reverse-ordered so that the most recent is always at the top. Currently, I add the cell, then manually move it to the top of the page, because I haven't figured out how to insert a cell at the top of the page automatically. I can insert between any two extant cells, but not before the first one. Is there a way to do this?
