Actually this would be version 1.1 as there are no big improvement. After using it for a while I figured that I could have made it better.

For instance, I have to use two wires to provide ground and vcc to the board. The whole point of this board is to ease the development of other boards by reducing the number of wires on the breadboard. So I guess I can loose those two wires and get power from the red and blue lines directly using headers.

The second possible improvement is on the mechanical side. Those tiny smd buttons are great but tiny! And they require quite a bit of force to be pushed. With the version 1.0, the headers are in line with each other so when I press a button the board bends towards the breadboard. Not really a problem but it should be resolved by putting headers somewhere else on the board. And so will be the power header.
