It was a great idea to create the drop box section, as this makes it easier to transfer decoration files to administrators, but also serves as a shared repository for all illustrations used on parts.

To extend this material database, you could also make it possible to upload vector design files (in a standard format like .svg)?
This would be useful sometimes to create variations of some existing decorations or perhaps also anticipate some future changes of the decoration format (quality, size, ...) required by the Mecabricks engine...
