I like the gCodeViewer very much. IMHO it's the best gcode viewer at the moment.
However, it would be nice if it would recognise G10/G11 commands as in the UltiGCode or volumetric RepRap flavour from Ultimaker. Also more and more other Marlin driven RepRap machines will use these commands as it has been implemented in Marlin recently.
thanks for this great piece of software!
Years later, +1 for this.
