With the price of Read/Writeable CD-ROM drives finally hitting the $150 mark, lack of disk space should be something easily avoided. I do agree that shuffling around trying to find that one model you're looking for is a pain. One extension I'd like to see in 3dE is the addition of thumbnail catalogs. In the old Image Pals program, when most of the archiving was to diskettes (really dating myself here), it would save a thumbnail of the image to the HDD in a catalog. If you wanted to use the image, IP would tell you which diskette to load to retrieve it. Scale this up to CDs and 3D models and you've got a system that would elimate much of that useless browsing. Not an easy task to build with all the 3D formats out there, especially if you wanted to include Poser files.
