Too slow for regular use. I am on a FAST G5 system, and the "sorting files" operation alone takes more than 10 minutes on a sequence of 1600 frames or so. If that problem were fixed and the following two features were added, then this would be the best renamer out there:
1. please add ability to preview before applying name change (to check to make sure settings are correct - look at the app "file renamer" for what I mean)
2. under "new name and numbering", have the interface copy the existing filename of frame 1 so that you can change it right there without having to re-type it.
