[Inkscape-devel] Save a copy in current dir?

Hi all, I'd like some usabilty input for this bug: https://bugs.launchpad.net/inkscape/+bug/791098

It requests an option to have the Save a Copy dialog always open in the current document's directory. The Save As... dialog already has this option (preferences > save).

Should I add an option below the Save As... dialog option in the preference dialog, or should I use the same setting for both dialogs? The reason I ask, is that I am a little afraid of adding yet another option...

Thanks for advice :), Johan
