One small bar above your player frame for healthstones, bandages, potions, elixirs, weapon stones, food, drinks and buff food. Each button uses the best item you carry.

Plain food and Well Fed food get their own buttons. The buff food button glows softly while you're not Well Fed, so you notice it before the pull.

Each button picks the best item you can use. Right-click it to choose a different one from your bags.

Food and drink step aside during a fight and the rest of the bar closes up. Cooldowns are easy to read, and every button can have a hotkey.

Sharpening stones, weightstones and oils go straight on your weapon with one click, Shift-click for your off-hand. The button glows while a weapon has nothing on it. Rogues get two poison buttons too.

Sort the buttons, choose which ones show in and out of combat, and bind a hotkey to any of them. The rest of the options (layout, look, reminders and profiles) are one click away in the sidebar.

Buttons glow gold when a buff or weapon stone is missing, and silver when it's about to run out, with your own timing for each. Counts turn red when you're down to your last few.
