It's currently impossible to tell how far up/down you're scrolled vertically. The notches at the top help show where you are horizontally, but an indication of where you are relative to how wide all the notes are would be nice.
Should add both horizontal and vertical scrollbars to indicate the current "dimensions" of the notes within the timeline, the current width of the viewport, and where you are within it.
