Collapsable/Expandable Text Box

[R2]

I'm writing a Data Flow Diagram and want to add annotations to the data
source but also want to keep the diagram clean and uncluttered. Ideally a
collapsable text box control or shape.

I'm aware of the Comment option but they're annoying to use because they're
a fixed size, don't move when then shape it's describing moves, and you can't
copy Comments (for example from one page to another).

ANY ideas?

I could also find a text box that crops text outside of the geometry
area very useful. I don't think there is a way to do it though.
Except ...
you could reduce the font size on collapse and restore it to normal on
expand.
