A feature that would delight me would be that my mouse and keyboard were also connected to each other. If I change which computer my keyboard is working with, my mouse would follow suit and not require me to turn it over with a second hand change the device number. I almost never need one without the other. I switch back and forth however all day between devices 1 and 2 and seldom 3. That means 1 button on keyboard directly to device but sometimes as many 2 button pushes on the mouse to cycle. Just a thought to really add some great option to what has become my favorite duo of tools.
