Enhancement, visual color for done, in buffer, pending

[sinfocomp]

Could it be possible to keep track of completed (executed) gcode lines, sent lines and pending lines, also view in visualisation the segments that are completed , the segments sent and the pending segments in diferent color, mabe a last line executed marker would also help in case of power failure.
Thanks Ed

if not visual, how about the line tracking to be able to correctly resume a failed job ?
