Transplantable Obstacles for the OCD
I'm sure I'm not alone in having a bit of OCD. I love the obstacles in the game but I can't leave them up. They appear haphazardly and my OCD goes crazy, so I just remove them for gems. My suggestion is to make them Transplantable, you can move them instead of removing them, but for a fee.
Next to Remove is a button to Transplant, let's say for 50,000 elixir, or maybe 1,000 dark elixir. You click the button and a confirmation box pops up asking if you want to Transplant, you move them and when they are in place, click Place, another confirmation box, and then it's locked in. This allows for making them aesthetically pleasing but at a cost. Even after Transplanting, the option to Remove or Transplant again remains at the same cost.
