Priest Rotation Helper

Tells you what to cast as a Shadow Priest - keeps Shadow Word: Pain and Vampiric Touch from ever falling off, uses Mind Blast the second it's off cooldown, and knows when Shadow Word: Death is actually safe to use (it hits you back just as hard if the target doesn't die). Mind Flay fills the gaps. Just an icon overlay plus an optional glow on your action bar, nothing gets cast for you.

Commands: /srh opens the settings panel, where you can toggle Vampiric Embrace upkeep or run the built-in test scenarios.

Checked the priority against Wowhead, Icy Veins, and Warcraft Tavern before publishing this, including confirming Devouring Plague and the other "classic Shadow Priest" abilities you'll see mentioned elsewhere are actually race-locked and not something most Priests can use, so they're left out on purpose.
