Do
These are the things Kawa is allowed to carry out, and they are the only ones. Each goes down a channel the shops already use — the job queue a manager's panel writes to, or a script that already lives on the server. There is deliberately no box here that runs whatever is typed into it: this page answers on plain HTTP, and such a box would be a root shell on the internet with five tills behind it.
Put the app back on a screen safe ← all
Something is covering a screen — Android's own "isn't responding" box after a half-finished update, a settings page somebody opened, a dialog nobody can reach. This takes it off and brings the ordering app back to the front, from here, without anybody walking to the screen. It changes nothing on the machine: no reboot, no settings, no orders touched.
