New velocity option for rotors/pistons/hinges
I've found I need to move backwards at a different speed than I do going forward.
As a solution, add an option to all three like the lock option, This option could be called "controlled Movement", Ticking the option unlocks two sliders that are otherwise grayed out by default. One for positive velocity, and the other for negative velocity. For example, Positive velocity at 10m/s but Negative velocity at -5m/s.
If you put the negative slider as a positive value, based on the fact it has its own slider not split in half, you'll only confuse players. Keep the values the same, we know forward is positive, and backwards is negative. Lol
