Just an idea.
I was thinking that it would be a good idea, if we could get a display/parse by attributes status.
For example, on "Preference Manager", filter by all devices that have humidity and display its current value. Or another idea, on "Dashboard" add all devices that have switch attribute status and recursively add all switch devices under one tile with the device name by the side.
It would help case like mine where I have multiple temperature sensors every room to be able to glimpse all sensors statuses all at once without having to manually browse thru them.
Think of it as a summary of a single attribute, common to all devices in the hub.
Or another one could be on the "devices" page, add a view by attributes.
