• Export multiple objects into different files all at once. The files will get the name of the object automatically so you don't have to rename them.
• When exporting in heavier formats like .glb, give Blender some time to export everything. This is not a magical add-on that reduces exporting times, it just makes it easier so you only have to press one button to export your entire scene.
