I'm glad you think so!  We think so. ;-)

We do plan to add the display of axes and major ellipses as well as a  
probability-level-to-scaling-factor calculator as well as session  
support.  What we've released is functional/useful but not what we  
consider complete at this point.  I'm going to open a feature-request  
ticket in our Trac database for axes/ellipses with you and Thomas  
Mitterfellner (who also requested these) as recipients, so you will  
get mail when it gets implemented.  My guess is it will probably take  
a month or so for me to have the time to implement it.
