The mod changes the way that quickbar swapping works when you have more than 2 quickbars. Instead of each quickbar being an individual bar, it groups them into pairs of 2 bars, and you can swap those two bars. You can then as you normally would swap the pair of two bars at the same time using a new shortcut SHIFT + X.
