Same! My use case is 2d splines for use in openSCAD, stuff that eventually arrives at my doorstep from a 3d printing service. I just love the ability to overlay reference bitmaps, super valuable for the parts I've been making.

Before stumbling upon this tool, I've spent a lot of time tweaking SVP paths in "mostly manual" files in other projects, it's a recurring theme for me. I was delegating the more interesting paths to Inkscape or similar, but keeping the basic structure handwritten. This tool would have made my life so much easier!
