With this update, the simulation got a new type of save file that improves both the loading time and the way the systems are loaded. At the same time, a new data type was introduced. The so-called "array list" enables the program to spontaneously add or delete planets. It's a work in progress, but you can test it out by pressing "j" :).  Also, the objects have been color coded so you can press "q" to see them to scale and then use "e" to see their new design.
