[REQUEST]Chip Shields

I thought that if I could plug a board (with an SD card slot in it) into the top of my Arduino, that the same could be done for the Chip!
I also want to note that a lot of people don’t want to have to plug everything through a usb hub. It would look a lot nicer if a board plugged straight into the Chip header.

In the new skylark version, can you at least offer compatible drivers for this?

Specifically USB and Bluetooth, but if you can think of anything else useful, go for it!
