A lot of discussion here about thrusters v vectoring engines.
They are actually the same beast in principle without going into what they are designed to accomplish and how they go about it.
Some of the woes to do with designing moving hulls are constrained by the DW2 Universal rules.
One major late decision was made in DW2 beta to halt ships to 0 speed instantly in order to solve combat issues related to being fun and have resolution. Immediate stops are not realistic, at least to my knowledge, and somewhat negate the need to have rapid weapon arc realignment, read: maneuverability. That decision made a huge difference in how combat resolved - there may also have been performance reasons as part of the line of thinking to have ships stop. I'd rather they continue moving and allow ships to have far better reorientation to maintain weapon engagement. There are also collision avoidance considerations that must have been part of that decision.
I've proposed allowing to add as many vectoring engines as there are possible thrust engines in a design as long as there is space, power, crew etc..., to allow for it. I would say let them, VEs, be internal components, under the maneuvering yellow section of the designer, to expedite implementation and 3d effects, but by all means let them be seen on the hulls if so be the desire

.
Having decided that the only tech available to alter a hull's orientation in time was to have vectoring thrusters, is another concept worth considering, there are other ways and also fictional ways to do that.
