Great software, but could I request a feature :
When engraving on a light coloured material (e.g. birch wood) the laser sometimes does not char quickly enough to start a track so the line isn't engraved. Another GCode generator (I think it's LaserWeb) has a 'delay' setting, which, after a laser off move, energises the laser then waits for a time before starting the engraving move. Sensible default for this would be 0 (i.e. no delay) up to 200 ms or so.
