Shieldwall

A group and raid addon for every role on WoW: Forever: a buff and debuff board that works in combat, a threat meter, threat-coloured nameplates, a tank’s mitigation window, gear sets, and a raid check of buffs and cooldowns.

Click a set to put it on, or /gs and its name in a macro; beside each, its numbers from last time, green or red against what you wear. Below, the mitigation window after a swap, each row's gain or loss. Taken at level 11, so crit is short.
Each buff your group can give, how many who need it have it, and on the tooltip who lacks it and who can cast it. Each key cooldown, how many are ready or when the next one is. Shown with the made-up rows of /shieldwall raid test.
With the tanking colours: green is a mob on you, red one your pet holds with little threat from you. Between them come yellow (on you, but only just) and orange (close to pulling). Every colour can be changed; the rest of the plate is Blizzard's.
Who is on your target, sorted, with whoever holds it marked. One line says what matters to you: here you hold it, one point ahead of your pet at 98%, so the line has turned amber. Not holding it, it says how close you are to pulling.
One settings window, a page for each part. Two sets of plate colours, for tanking and for everyone else, chosen by your role in the group or by hand; a change of colour blended over a moment; your target shaded by how close you are to pulling it.
