Hi!
When making proxy the collections are not an option in the proxy selection area. I can only choose single objects like the armature. This means I will have to make several proxies that just takes a lot of time. Is there something I'm doing wrong? I'm on blender 2.81 (latest official release from blender.org).
Also I was wondering, if making something proxy, like the armature, and then making changes to the armature, will I need to make it proxy again?
I am not good with proxies, but 2.81 has library overrides! Much better and easier!

You should watch it completely, but he talks about the library overrides from about 1h 07min.
