I've got an initial GUI with options - next step is to enable saving raster layers as embedded base64 encoded images. I also want to give the option to link raster layers, but one step at a time.
(My secondary goal is to make sure the SVG output is correct so I don't create new bug reports for Martin Owens :inkscape: :flag_nonbinary: (npub1wg8…q6l7) in #Inkscape !)
