MAtt, Chad:
I cannot see the "additional screenshots". Nothing in my inbox and I
don't see it here either:

help!

MJ> also static) into a separate advanced query dialog. 3) Eliminate the
MJ> slider -- she thought it might be useful, but probably too non-conventional.
MJ>
MJ> Some other stuff she comented on too: 4) The main workflow display MUST
MJ> have scroll bars, and the panning control should/could be moved to a
MJ> dialog/floating panel so that the tree has more real estate. 5) Ginny is
MJ> very used to using menu driven systems for selecting the statistics to
MJ> be used ona set of data. Her process for this type of app is 'Open the
MJ> data, select stats from hierarchical menus, configure stat, run'. See,
MJ> for example, SAS Analyst. So, she says that having the 'models' in the
MJ> tree on the left is really non-intutitive altogether, and those
MJ> hierarchies really should be menu items. I'm not sure if we can
MJ> accomodate that view, but she felt pretty strongly about it.
MJ>
MJ> So, in conclusion, I would probably vote for something akin to your
