The campfire supplies bar displays any campfire buffs you currently have in your bags upon approaching a campfire. The items will appear on a moveable bar, and you can click whichever buff item you want to place, and it will place it directly in front of your character. Also as well as tracks the rested XP progress of all of your characters in a separate window.
The alt rested estimator window tracks the rested experience progress for each of your characters in a separate window. It estimates the current amount of rested XP based on the location and amount of time since the character last logged out.
