Useable items shortcut: power regen, invisibility, healing, etc.

It initially frustrated me that there was only 2 slots for charm items.

Then I realized I could open a new hotkey bar and drag Totems and potions and clickable items like the Manastone, right to my hotbar, which makes them usable even when they aren't in the Charm slots. That means I can put my invisibility totem, my Manastone, my runspeed enhancing totem, my power regenerating totem, and others, all in hotkey slots that I can simply click on during combat.
