Save player view state
Re: Save player view state
Nope 
If you want to run the simulation for some steps and have the result reflected in the editor scene, you can look in the action menu under "Simulation" -> "Step all bodies". This will allow joints and stacks of bodies to relax into their natural positions, so that there will be no sudden jump when the simulation starts.
