Display node's languages in views do you think, it is possible to display in views the languages the node was translated to?
I mean something like this:

First article
english|german

Second article
english|german|dutch
Yes it is possible.

I have done something similar in Drupal 7 some time ago. Here is how to do it:

Create your View

Create a Fields style View with your required filters and sorting

Add the relationship to the Translations


Add a relationship to the translations: Content translation: Translations
As Translation option choose All
Add a filter Content translation: Language and choose Current user's language 


Add the Fields


Add the field Content: Title with no relation and with Link this field to the original piece of content disabled
Add the field Content translation: Language with the Translations relation added before and with Link this field to the original piece of content enabled
In the Format Settings choose Content: Title as Grouping Field


Format the list

The horizontal list of the languages can be achieved by CSS formatting
