Suggestion - More environmental data and consolidate sensors

I've seen other systems where the environmental sensors can detect more than one thing so you don't need to buy multiple sensors for the same room. I'd LOVE to see SS do this (as an option for people who want it, not necessarily as the only option) and also add sensor capabilities. For example, is there a reason we can't have fire/smoke and CO on the same sensor? Or that we can't have the temperature sensor also report humidity?
