Streamlining Drag & Drop Append from File Browser

Amazingly we can now append straight from the Blender External file browser or windows explorer by dragging and dropping. We can also see thumbnails of our blend files :slight_smile:

Would it be possible to streamline the dragging & dropping by allowing the user to Append All Objects or even Append All, which would allow us to avoid the extra screen where we have to choose further between different data-blocks in the blend file.

By allowing the user to skip that step the File Browser would become a very fast asset manager window.

Also, would it be possible to have textured thumbnails generated for .blend files so that we could create material libraries with previews simply by saving out different blend files?
