Since BYM added more buildings to the game, the Yard Planner v2 was the single most requested feature in the BYM Forum wishlist. For a long time now, Dave has promised the released of it. And in April 24 the BYM Team has started working on the new version as David Stated in a tweet.
So now we conclude that the arrival of the new version of the Yard Planner is inevitable. With features like saving base designs, better way to move blocks, turning on ranges of a specific defensive building and maybe more stuff.
Yes, it is a little tricky so solve the problems that they need to overcome to make this. But I guess the long wait is finally over.
Only time will tell and I think it will be real soon. It's been in a month on development since they worked on it and i guess they're done. They may add it this week or next week but one thing is for sure. It's coming and it's soon.
