I have mine set up to change the color of the last ticks of my Corruption, Immolate, and Unstable Affliction so that I know where the most optimal place to refresh is. This changes the last however many seconds of your bar to a different color. What I really like about this addon is that you can add a virtual cast bar to the end of your timer. With NTK, if something is missing, you'll know via a giant blank spot where a timer bar usually is. The position of every bar is static, so there's none of that sorting by time remaining or alphabetical order, where it could take a second to find what you're missing. You get 4 sets of bars (with each set capable of having anywhere from 1-20 bars), that can track pretty much whatever you'd like. I'll second the recommendation of NeedToKnow. Not sure what point Randa is trying to make, as he doesn't articulate very well.
