I hope that they also adjust the stack size of Crystals, I do a lot of crafting trying to get those fabled Dusk Gloves +1 and Arhat's Jinpachi +1 for my character and Crystals flood my inventory when I'm not crafting, of course I could delivery box them to my other characters on my account, but then if I want to send items to a friend who wants me to purchase an item off the auction house for them, I have to log out, go on to my other character, remove them from delivery box, and then go back on my main character and send them the item.

Perhaps even Stackable Clusters?
