The feature

I would like to request an improvement to the UI logic for the "Archive" and "Unarchive" buttons when selecting assets within an album.

Problem:

• ​Mobile app: The action menu always displays "Archive", regardless of whether the selected asset is already archived or not. There is no way to unarchive an item directly from the album view or to see its current state.
• Web interface: The "Unarchive" option is only displayed if exclusively archived assets are selected. If a mixed selection is made (e.g., selecting both archived and unarchived assets simultaneously), the "Unarchive" option disappears entirely.

This makes it difficult to manage photos in bulk.

Solution:

• Display "Archive" if there are only unarchived assets are selected
• Display "Unarchive" if there are only archived assets are selected
• Display both options for a mixed selection
• Display the current archive state in the app as it is done in the web interface
