I often use this tool (Rename Dialog, F2) for renaming the pictures to the name of the person and a continious number. It would be very useful to rename the files in a batch. For example: When i have a group of 60 people, i choose from anyone 1 picture. I have a filelist with the names of them. A copy paste error from the list to the dialog fails. It's only copy paste allowed inside the dialog what seldom benefits.
Another nice feature would be, a direct import or rename tool. Maybe also possible when you collect the pictures to stacks, it would rename the whole stack with the names in the list?
