Speed-Wiz has full-size calculation windows with a row of tabs along the top that allow you to view and select windows. Here you see Strategy, A-arm travel, Viewer, Compressor map, Help, and Convert windows are open, with the compressor map visible.
You can also use the MDI mode with windows that you can cascade and tile.
In the tabbed mode, you can create side-by-side groups of tabs. This allows you to view calculation windows simultaneously while still enjoying the benefits of the tabbed window system. Here we have a data log viewer on the left and an acceleration plot on the right.
Speed-Wiz offers skins to allow you to instantly change the entire look of the application to a scheme of your choice.
