Having the ability to group assets in the workspace into a folder structure would increase the usability of those assets, both in the 3D tool but also when creating a 2D layout. For example, our team has a large library of tools, arrows, and other supporting graphics. Needing to search through one large list of those for what is needed can be time consuming, even with the current tagging functionality. The ability to create fodlers and sub-folder would make locating a specific graphic significantly easier.
