I use CAD-CAM and generated g-code have 50000+ lines and a lot of G00 moves for positioning in 5 axis, so it's not practical to manually edit those lines. I don't have options in post processor to calculate those G00 moves with G93, it is only available on G01 and only when a rotary axis is involved.
Also it will be nice that g-code editor from Planet CNC software to have some functionality like notepad have, like go to line, search, find and replace and so on, else it's impossible to scroll trough editor to find where to edit. Or maybe when you double click on graphic area to jump in editor to that line like it does on the right panel.
