Hi there,
We are running a Duet 3 printer through a Raspberry Pi 4. As is well known, shutting down the Raspberry without command a "shutdown" can corrupt the SD and that's what happened to us 
Because of that, instead of access to the Pi via SSH, command a "shutdown" and then turn off the power source, we'd like to add a button into the web control interface to run the command easily. Is there any way to modify the web control interface?
Thanks
