GCode editor

[Speedy-Cuber]

I noticed that in the preview pane you can see the gcode as it is being "executed" line by line. This is an amazing feature, and I think that it would be even better if you could edit it from where it shows the gcode. I had to save a print the other day and this would allow you to make changes and see exactly where the toolhead will move instead of my method of opening up a text file, looking for the exact layer and editing the code and hoping that it works.
