If I for example want a thuster plum to face upwards and turn the thruster upwards, the thruster plum still goes from the back.

While your report is valid, it should be noted that I've seen several people, including myself, use rotated thrusters decoratively (in places where thrusters don't make sense). Since most people use crystals and lava as thruster replacements, I personally would like it to stay that way.
Bug confirmed, but I personally would like to not see that fixed. :D
