I read all the stuff about organising the MAT files (and other poser files) and was wondering about a little thing.... Could it be possible to assign, at the beginning of a MAT file (not in the filename, but in the code), the product on which it should work. It could be then possible to create a little program (python or something else) to create a "dynamic" library, showing only the MAT files (or pose, or figures, ...) working for a selected figure. This would be a great time saving and you could find free stuff you installed and forgot somewere in you gigabyte library...
