If you're anything like me and have ever forgotten to activate your symmetry planes on a symmetrical ship you're building, then you've experienced the frustration in having, well, half of or a quarter of or a eighth of whatever you're building, be it a station, a ship, or a minor detail.
Then you go through the agony of deleting and replacing every single block that you've already built to restore your structure to being symmetrical.
Wouldn't it be useful to have a nice little button that automatically mirrors everything you've built in one area along your activated symmetry planes? It's similar to the copy paste tool, but unlike it in that you don't have to go through the hassle of selecting the area you want to copy, spinning it around, and then finding the right place to put it in.
You just press the button, and it automatically fills in the areas that would have been filled had you remembered to turn on symmetry.
