Scene Collections Manager v1.1.2 [Blender Addon]

This addon allows you to easily manage collections and subcollections and is particularly suitable for well-structured projects with a large number of collections. Through this addon it is possible to create collections selections and save them in a special file so that you can reload the selection at any time. This way you have different configuration files, for example depending on the type of render you want to start or the camera you want to use, there are so many possible use cases.
