Currently, a player must click four times to make a single brick: one right click each for the hammer, chisel, and stone, and then a left click on the 'Craft' button.
If you remember that you need 80 bricks for a single wall section, this means that crafting enough bricks for a single wall section requires 320 clicks. This strikes me as 1) unnecessarily tedious, and 2) likely to inflict carpal tunnel syndrome on masons.
The simplest fix I can think of is to make the recipe call for 10 units of stone and produce 10 bricks, reducing the 320 clicks for one wall section to a much more reasonable 32.
Ideally, you wouldn't need to click the tools again between each crafting, but that's a wider issue than what I'm trying to address here.
