Please add the language selector to the site-tree datagrid. In own defined mutlilingual objects the languageversion dropdown is already shown in the datagrid. But it is not in the site-tree.
This would be extremely helpful. I'm currently translating a website with about 400 pages and I only can see if there's a language vesion for a specific language if I'm in the detail view of the page. It's really difficult to see which pages are not translated yet.
