Lovelace/overview duplication

It’s very easy to experiment with new versions of automations by making a duplicate and modifying it.

Similar functionality would be useful e.g. for creating from the all-encompassing Overview a simpler UI for family members who do not need full functionality by making a duplicate and stepping off all admin stuff. Also, a copy-and-paste function for Cards would be useful.

Copy & paste for cards is already possible, across dashboards.

And to copy a dashboard, just use the RAW config editor, select all and copy it. In the new dashboard go the same route and paste the YAML. Done! :slight_smile:
