In a project started with the Thunder distrib, I'm currently managing the permission of the "editor" group.

By default, it only have access to the content menu, and it's a good thing. 
But what if i want to give  permission to some children links (and only some specific children) of the others menu ?

**exemple :** 

I give to this group the ability to access, add, edit and delete some taxonomy terms. 

I can access to the relative admin page, but the `structure -> taxonomy` link in the admin Toolbar is not appearing. 

For now I have to manually create those links, but I think it's not the right way to do this because they will constitute duplicate link for the "administrator" group.

I suppose I need to give visibility right for the parent link "structure". But how ?
