The space shuttle system mod is a cool mod but honestly i really miss the Canadarm and wish it would work it could use magnet really wish it was revived and fixed to work for 1.12X. I also think another mod that is unique and wish it was revived as well is the space shuttle pack made from Mike-NZ not sure what happened to him but the mod Space Shuttle Pack on SpaceDock is unique because you could actually see stuff inside the cockpit transparent unlike the space shuttle system which the windows are black or unless one day someone adds an addon for it really wish these mods were revived.
