Lifesworn

A druid's frame in a fight: the missing health, Rejuvenation and Regrowth counting down in the top corners, the red aggro outline, the mana bar. Taken alone, so one frame; in a group there is one for each member.

Poisoned in the middle of a fight: the game draws the poison's green over the frame, and Control-right-click cures it from the frame. No icon: as installed, icons are for debuffs on Blizzard's raid list; the Auras page can show the ones you can remove.

/lsw test 25 draws 25 made-up members in your layout, so you can set it up before a raid. These are not real players: the names, health and icons are the preview's own.

Each mouse button, with or without a modifier, does what you choose on a frame: target, the unit menu, or a spell you have learned. The Rank list is open: "Highest" follows your training, or pick a lower rank to downrank on purpose.

The Auras page: the colour for a debuff you can remove, which debuffs get an icon and what each choice means, the game drawing them in a fight, and how your HoTs are shown.

Power Word: Shield on a priest at full health: the gold square counts it down, and the strip's pale blue line shows the shield where there is no missing health to fill.
