wouldnt it be possible to implement more than the -Token.
Perhaps as in other programs add "YY" (2011) "yy" (11) "HH" (08) "hh" (8) and so on as further Tokens.
Then it is possible that everyone can make its one "timecode".
I also hardly miss that feature, cause I us a format like "110207_filename" (7th february 2011) for my files, time is irelevant for me at that point ...
I think this feature should be easy to implement and will make PDF-Creator even bette a whole lot.
