Prijedlozi / Platforma za Greške

So basically when trying to sort my inventory like i would usually do by using side buttons of my mouse (button 5 for slot 1, button 4 for slot 9) i cant do it by just pressing them while hovering over an item, i need to drag them to the slot 1 or 9. And when holding ctrl and trying to switch to mouse 4 it registers it as mouse 5.
