How can i list all display suite layout templates used Is there a way to list all display suite templates that are currently being used in the various view modes?

To clarify: I have many content types, and many view modes, AND many custom made ds layouts. It's becomes a big mix and i would like to get an overview which ds layouts are being used by which view mode / content type.
I think he's asking to get an overview of of which bundle / view mode uses which template file.

That's currently not easy to fine in the backend - however this is something we want to add add some place.

The fastest way to get an overview is to go to the database and look into the 'ds_layout_settings' table. The 'layout' column holds the machine name of the template used.
