The Grumpy Elf: Need to Know is an addon that keeps track of things for you. I’ve been a long time user of the addon but never really used it on my hunter. Perhaps for various reasons.

Keep that priority rolling, try not to lose even a fraction of a second between any shots and worry about that one cooldown (outside of trinkets) named rapid fire.
Now that the world of hunter goodness has changed we are full of cooldowns and we should be using them all the time. If you are a good hunter you have already taken A Murder of Crows and Dire Beast and will be taking Glaive Toss at 90 not to mention getting Stampede at 87, all that and there is the addition of readiness for non MM hunters.
