Invites whoever says your keyword in a whisper, guild chat, say/yell or a channel - only the classes, levels, guild members or friends you pick. Raid convert and raid assistant too.
Every timed weapon buff - imbues, oils, stones, poisons - a shaman's shield and totems with who each one reaches, the elixirs you drink and your food, with timers, reminders and one-click reapply.
Combat timers in one block: your swings and the next enemy hit, cast bars, DoT bars kept per enemy, and the Overpower / Revenge / Riposte windows after a dodge, parry or block.
A Targets of interest panel beside the quest tracker: one secure row per mob your tracked quests want and per NPC to hand them back to - click to target and mark it - plus one key for any of them and a marker menu at the mouse.
Pick a dungeon and see how far you are from its door - and how far everyone else running the addon is - with the group finder's listings sorted by proximity and role.
