Last night, I discovered arc move.
Thank you, that made my day
It was one of those things that I implemented on a lark.
Shape mode for build-placement is also planned, so you'll be able to do it with turrets (assuming we ever get to it, knowing how much we have planned, but it's on the shorter list).
By the way, when setting up for wormhole defense, remember that most ships do not do optimal damage at maximum range, depending on the shields of the target. So pulling them in a bit from max range can help.
The funny thing is also had to ask myself "what does r do?"; z, I imagine, you were using to show the range of the circle of death.
One other note is that we have some plans for overhauling the interface for these more obscure commands; shift-q-v-right-click-drag-and-release... well, it works, but we need to find a better way
