When you need to see what has changed in a QuarkXPress project, try AthenaSoft’s FusionXT for QuarkXPress 9. This $79 XTension helps you compare and merge QuarkXPress project stories, assets, geometry and much more, side by side. Changes to the elements can be applied from one project to the other. It can even generate a preview of changes before applying them!
