Shield Maid is a tracker for the two Warrior abilities Shield Barrier and Shield Block. The addon helps decide what ability gives you the best mitigation for your rage points.
The addon adds an icon for each of the two abilities. The icons mimic buttons in indicating whether you have enough rage for each ability. When active, the icons show remaining duration for the buffs. The Shield Barrier icon shows remaining absorb value and the Shield Block icon shows total damage absorbed for the duration of the buff.
The addon calculates the estimated value of Shield Barrier if cast, by looking at your current rage, attack power and stamina levels. The addon also keeps track of incoming, blockable, damage and uses this information to estimate how much your Shield Block ability will mitigate if activated.
The most feasible ability is highlighted with a glow to make it easy to choose where to spend your rage.
NB: When comparing estimated mitigation values, the estimated Shield Barrier value at 60 rage is compared to the estimated mitigation from block (including critical blocks) of the last 6 seconds of incoming damage. This means that the Shield Barrier icon will glow even though the estimated Shield Barrier value is less than the estimated Shield Block value if the mitigation to rage ratio is higher for Shield Barrier.
No ingame configuration is available, but a few configuration variables can be adjusted in the Config.lua file.
Updated for patch 5.1.
Added an option to hide the frames out of combat. Credit goes to Mock for implementation tips.

The addon now dynamically loads and unloads depending on your class and spec.
Added a configuration option for frame strata that defaults to MEDIUM.
Fixed a small bug that would pause logging of blockable damage while Shield Block was active.
Changed the way Shield Block value is estimated. The addon now looks at incoming blockable damage and keeps a moving sum over the last 6 seconds.
