I'd even say, an option to choose what kind of things you want to be added to a skillbar. Like toogle 1st skillbar only for spells, 2nd for food and parchement, 3rd for food.
In single player, really need to be able to sell with the highest trader value whatever the character you have in selection, it would spare so much inventory management. And improve the crafting from items that are stocked into bags, this is insanely done actually. If you use the recipes it works fine, but if you try to combine various things, this is just bummer. Bags dont open everytime.
