I would like to see rigid body dynamics, similar to what is available to me through Autodesk Simulation with its MES capability, added to the Simulation module of Fusion 360.
This had been suggested two years ago by someone else but it was archived due to lack of votes then. I think, now that Fusion 360 is more mature and includes a growing Simulation capability, the addition of rigid body dynamics (mechanical event simulation) would be game-changing.
