I would like to suggest the ability to Move Lock Signs for free. Seems like I constantly need to move things a few blocks in some direction. Which gets expensive if you have 10 or 12 locked chests you want to move 1 block up. It would be nice if you could place a new sign for free after destroying an old sign... for a limited time. Either by delaying the 500 rupee refund or making the next lock sign half price.
