In 1.7 it was possible to rotate terminals and similar parts around their forward axis using a wrench,
which is especially useful when they're embedded in the floor or ceiling, given that there's no inherent "UP" axis in those circumstances.

This is currently not possible anymore.

This may be related to this issue as well. Ladysnake/BLAST#8 (comment)
Also, in the AoF3 Modpack, I noticed with the mod Block Shifter that I was not able to rotate around the same axis as above. I think these may be all related to access .FACING
