In the overview page "My Menus" include a space for "Recently deleted" menus with an option to restore them. Currently, once a menu is deleted, it cannot be recovered under any circumstances, even in cases of accidental deletion. This causes the clients to manually recreate a menu if it was deleted by accident, taking several hours and generating a new QR code/link that breaks signage and printed materials tied to the original.
A "Recently deleted" section (even with a limited retention window, e.g. 30 days) would prevent this kind of unrecoverable, accidental data loss and reduce support time spent on manual recreation.
This should include automated sub-menus too.
