When selecting a group of products in Product Viewer and selecting to redraw select products from database, there is a noticeable lag any time a product has a different spec group than the one previous to it.  It would seem that if the program could do a quick sort "behind the scenes" before redrawing (grouping products of like spec groups) it would cut down on the draw time.  For a huge job, this could end up saving several minutes for us.
