A screen that let's the cool air in, but keeps the nature sounds out (I'm not a Disney princess, I don't want to be woken up at 5am by birds).
Windows with built-in thermostats that close when it reaches a certain temperature. No more falling asleep to the awesome Fall-like air and waking up in the tundra! And while we're making shit up, let's add a rain sensor in to the design.
