Around late August 2007, Ed Burton and the soda team released Sodaconstructor II, an improved version of the classic sodaconstructor. It had a more standard interface, based around built-in features instead of the older sliders and menus built from scratch. It also allowed users to download, modify, and load the XML data used to store models, leading to some scripted tools being used for precise construction and introduced solid springs which masses would bounce off of. However, reaction was generally negative, as most users preferred the older interface due to its simplicity and flexibility. Another issue was the fact that due to small tweaks in the physics engine and XML format, some old models which relied on precise timing no longer functioned properly with the new applet.
