Hi everyone!
I've added a new control bar for starting/pausing simulations:
As well as being able to start and pause sims you can now use the forward and backward arrows to speed up and slow down your simulations easily. You will get a large frame rate hit if your computer has trouble running at the fast speeds, so you will have to find a speed that is good for your machine.
The back arrows only slow down the simulation, they do not reverse it...though that could be possible in a future update it would take a LOT of work for something I'm not sure people would want.
You will still be able to continue simulations after they have ended from the previous update and the other UI has been moved around to accommodate it.
Let me know if you have any issues using these new controls, and I will see you in the next update!
