Improve craters?

[SuperPotato]

Honestly, I love the craters, they're great!

But, they have some flaws which is water seems to bend with them instead of drowning them in a ocean or lake.

Also, please add tectonic plates but, make them quite slow and look nice and realistic (not making textures stretchy)

Seems a little unnecessary to have tectonic plates. Doesn't really fit in i don't think with the entire sim

Even crater dynamics is really beyond the scope of this simulation except is a very general way.  The combinations of relative velocities, angles, body sizes, and body materials alone makes it impractical to even remotely simulate craters.
