Display Current Location Control

Hi all,

I'm considering switching from cnc.js to Octoprint for controlling my Marlin based CNC router (MPCNC Lowrider 2). Through these forums and various plugins I've gotten close to feature parity with the cnc.js but the one thing that bugs me is that there is no display of the current location.

I know per the FAQ that it isn't shown because of the execution pipeline when a job is running and that it might be time delayed. This makes perfect sense for a 3D printer as jobs almost always have an have an origin at 0,0 and there isn't much of a job setup.

For CNC's its a bit different as you typically bring the machine head to the workpiece and often your origin is in the middle of a sheet of plywood. What I'd like to build is a plugin or control that updates coordinates in near real time as I jog the machine to the workpiece. It also serve's as as a safety blanket to ensure I've reset my origin via M92 prior to starting the job. I don't need to track the machine head is after the job starts just when I'm making manual moves via the keyboard so the plugin can disable itself once the job starts or just give delayed results.

Any thoughts on the best way to accomplish this? Thanks!
