In Inkscape they have a feature were you can add extensions and then use them in the program. I was wondering if you might be able to do something similar so I could then use the tabbed box maker or the living hinge directly in Lightburn and not have to switch back and forth to inkscape. By the way your program is fantastic , keep up the great work you are doing.
