Possibility to give explicit user rights below the default rights (less rights as default, outside the rights hierarchy)
We need it for one or two users (readonly) and we don't like to move the rights concept.
different usergroups on one page should be possible. read only for certain people. or blind for certain group
the right concept should be more customizable. this refers to list/form app, wiki contributors and task app.
the same manner as in blogs, admins should be able to create a user layer with strongrr rights
