Well... you would only have to type the node ID once, when creating the name of the sketch. After that, no matter how many times you upload that sketch, it will always have the right ID number automatically preselected on the OTA GUI.
Sometimes I'm in an upload binge for my 10 nodes, and more then once I send the new code to the wrong node.
By the way, for those to whom this hasn't happened yet, if you send new code via OTA to the wrong node, and that node is embedded inside the wall, you don't always have to dig it out to flash it with the cable and the FTDI interface. Just cut the power to the "right" node and upload the code using the wrong node ID again.
Perhaps this only happens to me, but it happened often so I dare think it may have happened to others.
