I added a proper playback console to ExoSim. The simulation can now be paused and resumed, reset to phase 0, and adjusted anywhere from 0.2× to 3.0× speed. The speed slider uses 0.1× steps, and it changes the planet’s orbit, the star rotation, the background movement, and the live graph together. I also enlarged the Orbital View so the 3D simulation has more room. My first version made the playback controls too large, so I reduced their height and width while keeping the speed slider readable. Pause, reset, speed changes, orbital phase, transit detection, and the light-curve marker now remain synchronized.
