There are so many different type of mats in this game that your inventory / FC chest fills up very fast. While I'd love for SE to give us a new section just for mats (like the equipment chest) I'd settle just for a button which stacks all the same material or ingredients automatically together, so a player doesn't have to search among hundreds of mats in the chest and click three times to deposit each individual item. Or even better, a deposit all button which takes all materials or ingredients from your inventory and place them automatically in relevant stacks within chests.
