How to list page translations next to the original in the same row?
Have a look at the Translation Management Tool, considered as the successor of the  Translation Overview module, and &quot;the&quot; module to move forward with in D8 also. From its project page:

... provides a tool set for translating content from different sources. The translation can be done by people or translation services of all kinds. It builds on and uses existing language tools and data structures in Drupal and can be used in automated workflow scenarios.
This module does not make i18n or any other language module for Drupal obsolete. It does only facilitate the translation process.

One of its community pages also contains some related screenprints, such as this one:

Plan B
Another possible approach that might be worth experimenting with, is to try to tune the View itself, by using &quot;rewrite results&quot; for each of the values in the columns with &quot;Czech&quot;, &quot;English&quot;, etc. And use these values to rewrite them to shown an image (like &quot;Czech.jpg&quot;, &quot;English.jpg&quot;, etc) with an &quot;Edit&quot; link below it. For the &quot;Add&quot;-equivalent you'd have to check what value you get for a 3rd language if you don't have a translation yet: if you do get something for that also, you could using a similar rewrite result, but then with an &quot;Add&quot; link.
