Dolphin in previous versions had the possibility to set for each user role permissions for any type of action such as: view, post, delete, edit, etc.

But it seems that now, instead of UNA evolving, they cut these very important functions and only "view" remained, if you look at the permissions from drupal you will see that any type of action can be set for any module and role.

This is one of the reasons why you can't do much with UNA, role permissions customization is very limited. Except for the fact that you start coding yourself.
