Book outline-List Own Book Permission

Currently this module does not have such a feature built in.

Maybe try out https://www.drupal.org/project/entity_hierarchy → ?

Entity hierarchy does not have the features and module environment that the book module has.
My question was very clear and understandable as you stated that there is no such feature in the current situation.
I can help more if you tell me what kind of information you need that isn't in the description.What other information do you need?

Will move to the current development branch if anyone ends up working on it.

This may address it ✨ Allow access to page to order book page's children Needs review but definitely should be addressed in ✨ Book module enhancements: better permissions Needs work
