New full-screen immersive mode: tap the simulation to fill the screen while keeping the orbit name at the upper left and live period, progress and position data at the upper right. Menus, orbit descriptions and gesture hints are hidden. Tap again to restore the interface. Smoother transitions eliminate the visual jump when entering and leaving immersive mode. Updated app icon. A transparent logo and app name now identify the simulation in normal and full-screen screenshots. The three-body guide now opens from a question-mark icon.
