Crud
After installing the module you will see the following menu. It is under the CMS main menu because I told it to be there.

1 for managing the entities, 1 for managing the entity attributes (because they are EAV) and one for managing comments.
You can even restrict access to some admins from the user roles.
The grid is a magento usual grid with filters and all.
It has an export capability and a mass action select from where you can bulk delete entities or change the status:
The add/edit form also looks as usual.
Because the entity allows frontend listing and url rewrites you will see an url key field. If left empty it will be filled in automatically based on the name.
For the Section entity, you will see similar screen to the category CRUD because it's a tree entity:
You will be able to select the associated articles to that section:
You can choose to select associated products.

If you choose to make your entities searchable in the backend you can use the global search to look for them:
