Delete Branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
I've made a shell script output with "sudo shutdown -h now" to shut down the pi safely, but I'd also like to send the g-code: "M117 RPI Shut Down" or similar to have a visual verification on the front of the printer on my LCD controller that the rpi is shut down when I power down the 5v to the printer. Unless I'm mistaken this isn't currently possible?
An option to add more than one item in "Controlled IO" would be nice.
