50% or 25% Speed Jetpack in atmosphere
Right now, the speed of the Jetpack is tacked to the highest speed on the server. I understand why, I really do. It's so that if you fall off your ship, you can always get it back. And I like that.
I also like that in space, the Jetpack makes life simple and easy.
But I think a simple enableable option in the server config could make a lot of people happy. An option to cut Atmospheric jetpack speed by 0, 25, 50, or 75% of the top server speed. This way, you can decide if you want an extra challenge, and if so, by how much.
I personally think that there's no reason to change deceleration values, but I do think that if you wanted change them then that should perhaps be a different option set.
