Since I finished the part I was working on, you were next on the list. No development effort needed only more experience in parts creation (which isn't simple but it is simpler than development). Your part had a number of errors in a number of places and was missing the color bands which core is looking for to modify (I don't actually know if it would break if they weren't there, but I expect so). So I had to clean up the svgs somewhat as well as change the metadata a bit to match (exactly!) Steve's original mini resistor to make Fritzing think this is a part of the core parts resistor family. Note you don't appear to be able to edit this with parts editor because parts editor will remove some of the needed meta data, so you need to be able to edit parts raw (which is normally how I work anyway). In any case I believe this will do what you want, it is your original (with some changes such as color bands added in bb, and the terminals cleaned up in schematic) but which Fritzing accepts as a member of the resistor family and will thus change the values (and the color bands in BB) for.
