I use filenames primarily for maintaining the order of files. (don't always use a playlist) The way ripperx creates filename (as opposed to grip) is 1.....9,10,11 etc. Thus in sort order, file 10 will come before file 1. It would be nice if ripperX could name files 01,......09, 10, 11 which would remain in sort order. As it is, I do a lot of renaming to name the files in this order. This naming would be for audio books and other where title names are not very important.
