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.
I see how this could be useful, but just planning your builds in advance will eliminate the problem. +0
+1000. With a time limit, I love this idea. Maybe within 2-3 minutes (or less/more) of breaking the sign, you can replace it for free. After that time it's normal price. To some extent yes. But you can't always plan everything.
I've tried planning ahead... Minecraft won't cooperate! I spend months on projects. It's hard to plan where a locked sign needs to be 3 months from now. My one project is over 8 months old. No sign is where it started out on day one.
