MAtt, Chad:

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

help!

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> 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> tree on the left is really non-intutitive altogether, and those
