Currently, as well as in old eZ Publish, it is not possible to remove all content locations in one go. If the content has more than one location, and the user moves it to the trash, then in fact only that particular one location is moved to trash (removed if user cleans trash).

This is very uncomfortable and time consuming for the editors working on the content in the customer's installation.

Note from the customer:

With a note to its prioritization, it is worth remembering that it is seemingly small deficiencies like these which undermine the quality of the entire eZ Platform user experience, meaning that any new features won't impress upon our users that this is a quality, enterprise, product.
