Add 'Room' to Device data and allow filtering

Any value to making "rooms"

Has anyone found value in making Groups that contain all the devices in a room? I feel like every other Home automation platform is heavily based on the concept of rooms, but Hubitat seems to eschew this completely. I'd really love to have tags and filters in the device list, but that's more of a feature request Does anyone else make/use rooms in any useful way?
