Thank you for your suggestion regarding the ability to hide or exclude files from translation in specific language pairs within a multilingual project.

While it’s not possible to generally hide a file per language pair after publishing the project, this use case can already be addressed by assigning only the bilingual files relevant to the appropriate language pair during the assignment. This allows you to control which files are worked on in which language directions, without needing to unpublish the project or risk losing assigned users.
