Galacticraft 4 doesn't support SmartMoving. Galacticraft 3 did though and very well (thanks to @radfast) because SmartMoving was stable and available for Minecraft 1.7.10, but it stopped being maintained probably around MC 1.8.

Now there are some SmartMoving ports around but, from what I see, they have some issues. There's this https://github.com/Elveskevtar/SmarterMoving which looks promising, but there's no plans to support it for the time being.
