You know how we have tiny icons for "visible" and "selectable in viewport" ?

It would be very useful to see at a glance which lights have shadows/volumetrics on. It wouldn't even need to be an icon, it could just be gray italicized text in parenthesises after the name of the light.

It's just something I thought about after hitting the "max 16 shadowed lights" limit just now! I was trying to determine which lights I could safely disable shadows on, but with about 30 of them (please don't judge me), it was a tedious task.
