I'm sure I could list plenty of things if I gave it more in-depth thought, but one suggestion I have more immediately is increasing the weight of the backpack to around 751. I say this because, if you buy and equip the fanny pack, rather than the backpack dropping to the ground for quick access, it goes into your inventory, where you then have to go through the extra step of manually dropping it there. A needless hassle, imo.
