This should probably be one of the last things to implement before the full complete version is released, in the mean time, there should be some things to update each at a time, first being the oblateness, second being the textures, random textures are fine for fictional or exo worlds, but not for worlds like Ganymede, Callisto, Dione, Tethys, Titan, Iapetus or the main Uranian or Neptunian moons, yet Earth should have more clouds and have a darker texture for its oceans, yet Jupiter, Saturn, Uranus and Neptune should look more realistic, Venus should have its own cloud texture and not that of Earth's, same thing goes with Titan, Saturn's second largest moon.
Those should be done first before improving the impact effects, so take your time.
