Smoother beaches, Ocean waves, Tides, and rip currents

I think this should be added because oceans are just dull plain standing bodies of water, and that's really unrealistic.  Beaches are not smooth once you go to the beach there's just a drop off then your at the bottom of the ocean, and its unrealistic

The ocean should have currents that repeatedly wash up onshore. Once the current hits land, another current should show up 20 blocks away from the shore. 

Rip currents should pull players away from shore, and pull them underwater. They should happen at any beach, anytime.

Beaches should be smoother, and when you get in the water it should start off 1 block deep and when you go 45 blocks further it should get deeper and deeper.

Every 3 days the ocean should rise 6 to 9 blocks high. This is called high tide.  After 4 days the ocean should get 10 to 19 blocks shallower. This is low tide. At low tide, there should be more animals and fish.
