I created two the same pages:
1. one in Russian
2. one in English

Now I'd like to have one more facility to my admin-panel (red outline):
http://www.archinoma.com/media/photo/admin.jpg

In public page it should display this way (for examlpe):
http://www.archinoma.com/media/photo/public_page.jpg

How is it possible ?

Sorry, if I ask too much
(But I didnt find other comfy solution about switching languages among pages)
