XnView Software

I mostly use xnview for doing batch changes to my Images, mostly resizing, and I like to keep them in a Subdirectory of the Path where the Images are stored.
Therefore it would be a great addition to have a second Field next to "Wie Eingabeverzeichnis" (sorry only have it German - but it should be something like "same as input folder")
[x] Place in Subfolder [_________]
