EventAlert 

The addon will notify you in the middle of your screen with an icon, name of the spell that has procced, the time left on the proc and will make a subtle sound. EventAlert is also able to handle more than one proc at a time (this option was not available in previous versions).

I am not fond of addons that have very complicated installation and setups. The mod should work on install without any config, but if you wish to change any options use the following command: /ea options
To see a more detailed list of what options are avaiable to the mod, just check out the screenshot of the options pane.

Quick Backstory: I created this addon as a test for myself as my first "from the ground up" addon. Most of my coding in WoW LUA was taking other addons and just fixing them so they work from minor bugs or whatnot.

Anyhow, I needed a mod that was lightweight and did only what I wanted it to do, and that was warn me when one of my spells or talents procced something I needed. Thus, EventAlert was born. There are likely to be bugs, explosions and not so good things that may come from this mod. I'm sorry in advance! If you find a bug, please let me know so I can fix it.

Also, if anyone finds a spell/talent/etc that they want watched, please let me know and I will add it!
