sophisticated renaming based on existing file names via regex and masks. can use file metadata regarding time (creation, modified etc).
there is ONE very special feature of this tool which I will keep it for. in mac OS, it allows the altering of "date created" to any arbitrary value. I looked for how to do this a while ago and the only solution I found was to change the clock on the computer to the target date, do the thing, and change the clock back. tres unsleek. I knew that couldn't be the only way to accomplish this. somehow this developer has done what no one else could do.
