I have just committed a patch for the gtkmmified preferences dialog it's not finished but it's ready to replace the old dialog.
Todo: -Enable opening of dialog by doubleclicking toolbar buttons. -Add access keys to all labels and widgets (HIG chapter 10) -Add icons to the pagelist -Fix bitmapoversample (add to preferences-skeleton.h) -Change dialog title to Inkscape preferences (HIG chapter 3) -Move menu entry for inkscape preferences from file to edit menu. (HIG chapter 4) -Add dialogs.showclose preference -Investigate this http://sourceforge.net/mailarchive/message.php?msg_id=14240882
About Adding access keys to all labels and widgets, this would break all translations so i'd like to know if we really want this before i go ahead and do it.
I'd welcome any comments on the dialog and the todo list.
