Mark completely translated items in the plone toolbar
It could be a nice feature to mark elements that are completely translated into all available languages with a blue icon in the Plone toolbar, instead of the white one! It is done similarly now in Plone5 with published/private elements.
I think this could be an important information for editors, to have an overview at first sight.
sidenote: I posted this already some days ago somewhere else (https://github.com/plone/Products.CMFPlone/issues/1261)
