This has such a huge footprint. All Goog would need to do is look for
or similar code, and blast everyone using it.
At the very least, if we could define our own letters to replace "dfr", as well as any other footprints that may be lurking about (I haven't delved into it yet), then that would be a help. Just a form field (or two or three, depending upon how many variations of footprintable classes are used), where we could supply our own letters during setup, would be all that is needed. There may be other footprints that this wouldn't cover, I don't know, but it would be a good start.
