@falktx @prokoudine @GIMP @inkscape If you mean, having both vector and link layers in a same image, sure.

If you mean having a link layer which you convert into a vector layer (editable in GIMP), it's of course theoretically possible, but the problem is that GIMP is not a full-featured vector-first program. Our path tool is quite limited and if you were to link a complex SVG file with advanced vector feature, we'd likely lose some of these in a conversion.
