Add legend to indicators

Hi there,
I’m a happy HASSIO user and wanted to ask if it can be possible to add a small legend near indicators.
Below a screenshot of what I’m talking about:

I set custom thresholds but if I don’t check the configuration of the card itself, I can’t get the exact value of the thresholds.

Can this feature request be accomplished? Or eventually, do you have any clue on how to add a mini legend near it?

Thanks :smiley:

P.S. Will it ever be possible adding custom threshold values rather than the stock three ones?
