I like the idea of adding a new property type, but I wonder if it could be
generalized to more ID types (Object, Scene, etc.)
Maybe something like this:
bpy.props.IDProperty(subtype='OBJECT') # to store an object
bpy.props.IDProperty(subtype='SCENE') # to store a scene
bpy.props.IDProperty(subtype='NODE_TREE', type=NodeTreeType) # to store
a node tree
Would a property like this make sense?
Thanks,
