I just added a switch to the board that works as a manual reset. In the old design the switch was missing and the idea was that you could just replug the USB to powercycle and enter bootloader mode, but after some time thinking about all the consequences I decided that it was too much of a hassle and also would mean you can not plug the board into a socket when supplying power over the pins or you would need to add an external reset switch.

Since I wanted to provide a full Arduino stack this would cause too much trouble to the user and would influence the ease of use. for this reason I added a tiny switch but needed to remove the power LED to fit it on the board. the other LED is still available. I also needed to rotate the ATTiny to the original orientation which is quite a bummer since I liked the way the rotated chip looked on the board.
