A feature where I can put notes along my graph to signify benchmarks to qualitatively, rather than just quantitatively, see my progress...

For example, if I am trying to lose 100 pounds and set up a Beeminder graph accordingly, it'd be nice to have a note or symbol or any visual/text benchmark at the point in the graph that tells me "10 lbs Lost!"

This breaks up any big goal into benchmarks to steer my graph toward-- rather than just having a bulls-eye somewhere in the distance that I can't even see just starting out.
