Star browser: generation of a systems is moved to parallel threads. Now it uses all the CPU cores, filling the table is a few times faster (depending on the number of additional cores), and FPS is not affected. Maximum count of stars in increased to 10000. On the Core i7 @3.8 GHz, all 10000 systems are generated in 30 seconds (7 threads for the generator and 1 thread for the renderer).
