It should happen the next update!
This is a major, game breaking issue that needs to be addressed NOW!
Without a way to manage the large amounts of stone that result from delving lodgings, players are forced to either just let the stone sit around, make a massive stockpile for it (Which results in even more stone if they delve another room), or make a quantum stockpile to stick it in.
Every single option is game breaking
1. Letting it sit around tarnishes the beauty and splendor of the delving's players are trying to do, and is very immersion ruining.
2. Creating a huge stockpile for it makes the fort looks both A. Ugly and disproportionate, B. Nearly useless because every extra room delved makes more stone, so the stockpile is quickly filled to it's limit, requiring more space to be delved to expand the stockpile, which makes the fortress look more ugly and disproportionate and in the end produces more stone you don't have room for.
3. Creating a quantum stockpile is immersion ruining because you have to use the dump function for something that it was never intended for, turning it into a game breaking exploit.
I'm not gonna let this issue go, from now on i'm going to let toady know that his game is broken because he hasn't implemented crates yet.
If he wants his game to be not broken, he needs to implement crates post-hastes, in the very next update.
They're just bins with a different name and a different function, Toady, it shouldn't take you more than a day to implement them.
