sounds good. always looking for good examples.

i really like the property dialogs. we need better icons ;) and we'll need to 
do some work on various widgets - like class selection and stereotype

it might not hurt to provide definitions of some of these things - i'm not 
really sure what they all are. i know what drill down is. i suspect that roll 
up is moving to a higher level of abstraction. slice and dice? creating views 
based on dynamic queries?

if we can find ways to support these visually, we'll do it.

there won't be any 3d :) it was just an interesting analogy.
