1a) When I pick the FUD, material, the preview looks terribly bumpy.. not nearly as smooth as FUD actually is.
1b) Upon further review.. get rid of the bumps on all materials.
1c) Some sense of scale for the items would be helpful.. how about adding axis rulers?
2) Why two scrollbars?
3) The "Show More" and "Show Less" button should have an outline, indicating that it IS a button.
4) In fact, I'd prefer that the Analysis just be open all the time.... make the Materials window smaller.
5) Why not have "Show More" on the list of materials? And/or a filter for only specific materials?
6) Is it possible to move the name of the model (and possibly the Model#) up to the top banner?
7) Is the list of materials going to show when a model has some issue? Often, my models are fine in one material, but have a problem in some other material. I'd need to see which ones pass/fail.
8) Put a box around "Qty:1" .. it looks like it's offset to the left and would look better if it lined up with the text above.
