Core Sankey chart improvement suggestions

[tomlut]

I just noticed there is now a core Sankey energy chart. I assume this is a work in progress as I can't find any documentation on it.

Things I like:

• Automatic set up using floors and areas. Amazing! Well done. So much easier than the 3rd party card.

Things that could be improved:

• Please use the standard core card title CSS that other cards use so we don't have to make style modifications to every different card type.
• Please consider showing all grid sources
• Please consider showing numeric values
• Please consider allowing clicking on the nodes to go to pop-up more info cards.

Complementary to the previous.

Things that could be improved:

• Add power usage (select DEVICE__power usage instead of DEVICE__energy).
• Possibility to (automatically) add more device measurement groups, like temperature/humidity/etc.
• Option to show automatically created YAML code (when implemented).

There is some documentation on it now: https://www.home-assistant.io/dashboards/energy/#sankey-energy-graph

Nice.
Just needs the extras requested.

The ability for the card to be stretched to fit the new sections view

[tomlut]

That is already possible. Set the section to the number of columns in your view and set the card to full width.
