    Re: Precomp Navigation

    Hi again. This time with a not-really-urgent-at-all request.
    
    I use a rule mainly for trig. It would be a nice touch if the main full-degree 
    marks also had the complements of the angles ala K&E. Doesn't have to be 
    colors, maybe italics for the cosines.
    
    You've got a great product. The other thing I like is it's so easy to look up logs.

    Makes the $13.50 just for Precomp look somewhat expensive.I don't remember 
    where I got my copy from - perhaps through the RIN, and I'm sure it wasn't 
    $50 at the time.John
