Hey, Bohemians!
The feature / gameplay element I'm talking about last worked in 1.02:
When you pointed a fence kit at any geometry above your eye level, the fence direction would line up with your line of sight, allowing you to build all sorts of neat structures (provided the server allowed such fence placement), including horizontal platforms as the parent Task was asking for, see my imgur album:
Ever since 1.03 however, fences always point UP, regardless of where or how you attempt placing them. The only benefit is an easier way to make them straight I suppose, but the possibilities of an adjustible fence as you can see in the imgur album are endless and were fun to use.
I would ask that you revert the placement dynamics back to how they worked before, and maybe just make the "focus" modifier key straighten the fence kit upwards to help out the people who can't into fence-aligning-along-some-item-that-you-drop-for-a-sec.
