Basic question here...I'd like to use notes within sketches to clarify intent and label various elements for documentation purposes.  Things like "This inside edge should not be smaller than ...".  The idea is to be able to run through the sketches in six months or a year and understand what's going on quickly due to the notes.

I can only see two ways to do this.  One is to simply use text, which is far less than ideal.  The other is to use notes, which would be great except that I can't control their visibility very well.  I only want my notes to show-up when I am editing the sketch or when I double-click on it (just like dimensions show up).  Is there a way to do this?

Thanks,
