Hypothetically, I've just created the greatest Blender scene of all time, and there are thirty-seven meshes spread across twenty two objects that I know I want to archive in my personal library of really, really useful sub-objects. Now, I know I can save the scene, open a new instance of Blender, and append those sub-objects into a new blend file. But it would be faster and more efficient if I could just select the items I want, and save them to a new Blender file, without having all of the other parts of the retinue included.
I haven't found such capability. Is it not there, or did I just not look hard enough to find how to use it?
