We have a site with a lot of community-generated content, and only some of it we intend to translate at all. It would be great if translation_overview's list could be restricted accordingly.

I looked into translation_overview, and it is just great since the translation workflow it leads to is much more flexible, simple and lightweight than that of tmgt. However, I miss an option to show only the content we intend to translate at all. A simple and straightforward way would be a configuration (or filter view) option to ignore all nodes with a "language neutral" setting. Because normally, such nodes are considered to be irrelevant for translation: both the translation (Content Translation) and entity_translation modules will only show a "Translate" tab for nodes that have a defined language.
