How to rapidly identify translated items (or not) for a lang translator?

The old mechanism available in previous edition of Jahia to display available but still not translated content (displayed with N/A or so) is no more available in 6.5.

However it now becomes harder for a translator to guess which content item is already translated or not yet. He constantly needs to switch from one lang to the other to check is a "module" is missing. This is quite easy (but time-consuming) in simple page with only 1 or 2 main_content but this might become much harder on template listing hundreds of entries.

If easy to implement it would be nice to have such a permission in the role, so that the sysadmin can turn on "to-be-transalted" wireframes (similar to the ones existing for empty areas) for the translator role.
