I just made about 16 different types of signs at the outpost to organize my storage, and to my disdain, the tooltip AND the placement icon just say "Signage." PLEASE have the tooltip and placement icon show the actual graohics of the sign, This trial and error is killing me.
Yes also an updated way to create/edit these signs like more controlled/precise way to select colors and indication which pixel is being hovered to color or pick from.
