just try it and notice that it mods the weapon kills in the 'dog tags > title' section. i put each weapon kill for 2000 kills and once i enter the dog tag section i got an achievement for a level-four title. each weapon listed in the editor, for me now are level-4 and it says for 1000 kills in game.
i hope you can add modding the weapon stats the skill shop use and the other weapons in the title section.

anyway, nice editor.
