Hello!
I love the advanced Renamer function. Of course it requires quite a bit of studying, but since for many years now I've been relying on third-party tools to do my renaming, it's really great to see some advanced functionality incorporated!
I'd suggest a couple of additions that I find very useful and are found in every renamer I've ever tried:
-insert string at position ## in the filename, or insert string ## characters from end of filenames
-remove xx chars starting at position ## or backwords starting from the end of the filename
Thanks for this great addition to DO!
