Easy export and import of materials .d5m

Thank you for allowing us to export and import materials in .D5M format as easily as it is possible for objects with the .D5A format. I know that these files can be retrieved from the material source folder, but that is not an efficient way to work.

Additionally, when creating dozens of categories in the local library and renaming them in the software, it is very frustrating to see that all the local folders on the PC do not retain the category names from the software. Instead, all the local folders on the PC are named NewCategory followed by a number, and they do not even follow the chronological order of the library.

These two issues significantly reduce productivity, especially from a collaborative workflow perspective.
