The aforementioned YouTube video is about the VEXX CAD program included with the Gearotic software developed by Art Fenerty.
I would like for the Lightburn program developers to watch the video in reference to the scissors (snip tool) detailed in video from the 5:40 to 10:30 minute mark. This is by far the best variation of a snip tool that I have seen. I know the programming of the snip tool is already underway, but you might be able to include the different scissor modes in the Lightburn software.
The whole video is 25:41 minutes long and is well worth the time to view the way certain node editing and other tools are implemented.
