The feature

Description

Currently, album collaborators with the "Editor" role can add, reorder, or modify album content, but they cannot delete photos from the album itself.

This makes collaborative album management less flexible, especially for shared family or team albums where a contributor may need to remove incorrect or duplicate photos without needing full ownership/admin rights for the whole library.

Problem

Album editors are trusted to manage album content, but they are blocked from removing photos. This creates a mismatch between permissions and real workflow needs.

For example:

• a shared family album has multiple contributors
• one editor adds the wrong photo or duplicates
• they need to remove it quickly
• but they are prevented from doing so unless they have broader library-level permissions

Proposed solution

Add a permission for album editors to delete photos from the album they manage.

This should be scoped to the album and should not grant:

• global library deletion
• permission to delete photos outside the album
• access to full admin-level album ownership changes

Expected behavior

• Album owners/admins can manage permissions for deletion.
• Album editors with delete permission can remove assets from that album.
• Non-editors and viewers cannot delete assets.
• Deleting an asset from an album should not remove it from the entire library unless explicitly implemented as a separate, higher-privilege action.

Use cases

• Shared team albums
• Event albums with multiple contributors
• Family albums where contributors need to clean up content
• Collaborative curation without giving full library admin rights

Acceptance criteria

• Album editors can delete photos from an album when enabled by the owner/admin.
• Deletion is limited to the album context.
• Owners/admins retain full control.
• Existing permission model remains unchanged for viewers/non-editors.
• The behavior is documented clearly in the permissions/UI.

Additional notes

This could be implemented as:

• a separate toggle in album permissions, or
• an extension of the existing editor role with optional “delete assets” capability

This would improve collaborative album management while keeping destructive actions limited to the appropriate scope.
