In a Design file's editor, More now holds Move to another team, Duplicate and Archive. Open an archived file to find Restore and Delete Design in the same menu; Restore opens the file again. The Design files list no longer has these buttons on each row, and a click anywhere on a row opens the file.
Duplicate, archive and delete a Design file from its More menu
A Design file's editor has a More menu with Move to another team, Duplicate and Archive. An archived file has Restore and Delete Design there instead.
