Minor UI bug. When I click GCODE View button before loading anything (straight after starting LW) it loses the X & Y axis rulers on the viewer.

So far, after loading any type of gcode (produced by inkscape plugin) I never see anything in gcode view.

I will Peter, thank you.

FWIW in smoothie (and I presume elsewhere) the S value is modal like the F value, so a G1 without and S value would use the current S value from a previous G1 that had it specified. Maybe the previewer should do the same?
