Blender batch exporter and batch renderer

I require a custom Blender add-on to be able to read the outliner's heirarchy and export each collection as a GltF file - with some small features.

This exporter must
-> use most recent GLTF export settings
-> use the name of the collection for the exported file.
-> be able to handle linked geometry in collections
-> export to folder structures (in windows) to match the outliner

(as a seperate function)
-> render an image of each collection, using the same name in the same folder, using the scene camera.

A sample .blend file with all needs is prepared if needed.
I can also supply open source scripts which do something close to this.

Deliverables
Create working Blender exporter/renderer based on project needs
