You know that last update, right? Where you can hold 1, 2, 3, 4, 5, 6, 7, 8, 9 or 0 to assign a block to your "Level Bricks" bar.

– Block selector
In your block bar, hold down a number key (0-9) and click a block to assign it to that number on your quick bar.
This also works as a block picker on blocks in the level!

So, actually, there are some problems.

1 - Open inventory, press 1 and click any block on your inventory that you can put there. You usually have to click twice, since it bugs a little.
2 - Hold 1, 2 or whatever key and click on a world block. You now have it on your toolbar (if you own it). But, if you hold 0 and click (using world picker), you will place a coin (or whatever block it's there) on the world, instead of assigning it! (This bug is fixed on inventory)
3 - If you try to assign a background, you will assign an empty block (gravity)! But if you try to assign a background to 0 you will place the block you have on 0 on the world!
4 - If you don't have a block, hold 0 and try to assign it (using world picker), the same thing happens: you will place a coin (or whatever block it's there) on the world, instead of assigning it!
