I went through all my products and made sure each kit had two previews - one with the designer/kit name and the other named folder... and then I switched to Windows 7 and the folders show up differently and the preview won't show up the same way anymore
.
What I'd love is if the designers named all the papers and elements with their design name & kit name. When I drag them into CS5, it renames the layer with the name of the paper/element and it's wonderful for credit tracking to have the designer/kit info available that way. One of these days, I'll get around to renaming them myself - I just haven't gotten around to it yet.
