From the editor point of view is usefull to know wether a post have or have not a translation to a specific language. Also is good to have a quick overview of the translation status, knowing at a glance how many posts needs translation.
In my plugin there was 2 shortcuts for this:
One in the post listing, as a new column, showing the flags of each language and a PLUS icon to add a translation or a pencil icon to edit an existing translation. (screenshot at http://hacklab.com.br/files/2012/11/Seleção_004.png)
The same flags were present in a metabox inside the edit-post page.
Also, in the edit screen, there was a metabox with the full text of each translation for that post. This is helpfull to the editor so he can look at the post he is translating (screenshot at http://hacklab.com.br/files/2012/11/Seleção_005.png)
Note that using country flags to represent languages can be mis-leading.
For example there are many countries which speak English, Spanish, Arabic etc... so which flag do you use?
