Honestly I'd love to see some customizable settings added to the game.
Such as adding a setting that allows you to change the max item stack size, as in having a setting for each item category. An example would be for arrows, you would be able to increase stack size to whatever you prefer so maybe like 100 or something while the stack size is 20 for normal items like materials and such. That would make a great addition for people like me who like to use custom settings.
It would also be great if we were able to change the maximum haul size in the custom settings.
