An extremely simple addon that simply gives you a text display of how much your Shield Barrier absorb will be worth if you activate it at any given moment. Options can be found in the Interface -> AddOns menu. Configurable font (via SharedMedia), font size, color, and position.
I don't even know if 5.0 broke this or not, but the repository is open if anyone wants to fix it. Displays an ordered list of Searing Seed timers for your entire raid during the Majordomo Staghelm encounter. /sst for options.
