One thing that's always been an annoyance has been moving materials over to different characters. Sometimes I'm upgrading a weapon or piece of armor and I only need a few more Relic Iron or I just need a few Heavy Ammo Synthesis from another character to do a raid or strike. But the only way to get those from another character is to move the [b]whole entire[/b] stack to my other character. And in doing this, it also absorbs whatever small stack I had on one of the characters. So I'm ended up with an even larger stack of materials/items, and left with one character not having a stack at all. If I have a stack of 50 Heavy Ammo Synthesis, it would be a huge convenience to be able to just move 25 of them to a different character. It would make inventory management across multiple characters so much easier. All you would really need was a dialogue box asking "How many of these would you like to move?" Or something similar to that effect. And pressing triangle/Y could be used to specifically do this.
