It would be great to have a feature to export (save) the contents of the main (Location, Original Name, New Name) list control. That way you can have a permanent record of the files' name states. There are other uses for this feature. For example, I may have a list of files that have long complicated file names, but I want to rename the files to be much simpler (numbered files with simple base names), but have a list of before and after so the new names act as sort of codes for the originals. This would be great for other automation stages, too. I've never seen this feature, so it would set metamorphose apart.
