For more complex dashboards, showing informative instructions can take up some major screen real estate. I find on first pass a user may want detailed instructions, but after they know how the dashboard works, they want them out of the way, instead of always having to scroll past them.
As a model builder, I would like the ability to give them a textbox that unrolls to a larger field of text when the user hovers over it or clicks it. Once they leave it or click it again, it should roll up out of the way. However they should be able to click a pin to keep it open.
