I would like to see scanfolder plugin to be able to choose per folder different save location.
E.g. you can add a scanned folder "A" and to this would apply group "A" with different save location than scanned folder "B"

That way I could use my current workstation as torrent server with multiple users - each have access to it's personal samba folder, which is scanned by ktorrent. So that way those folders would mean different groups and save locations.

Currently you can define only on save location in scanfolder plugin settings - it doesn't apply per scanned folder.

Would it be possible to implement this?

It's possible, we could add per folder settings, and the global settings would then become default settings.

However when I can get to this, is another matter.
