Fantastic stuff!!!
Just a couple of points. I've noticed with both GUIs the expand (maximise) button isn't working?
This isn't a big problem unless you're working with long directory strings.
Also, mousing over first/last in the "Renumber" box (in PCFE) doesn't tell us what those two options (first, last) mean??? By default "renumber" box is ticked and "first" is also selected.
Otherwise, this is really coooooool stuff
