An overview is given of Q+, an interactive tool for performance modeling that uses graphical input and visual output. Two major enhancements are a subnetwork capability for structuring models hierarchically and an integrated expression capability. New capabilities are custom icons and temporal browsing. With a Q+ icon palette, users can draw their own icons and manipulate existing ones. The browser allows browsing, editing and updating Q+ information, which can be textual or graphical. Automatic model building, operations management, and experimental design with Q+ are discussed.<>
