This project started as an update to Feral By Night. I have been using that addon for quite a while and really liked certain aspects. In refactoring and updating the code for Cataclysm, I ended up deciding to start from scratch and build a similar addon, without the cruft that I don't use and with a focus on performance and maintainability.

Features

Super Low cpu utilization
Shared buff/debff frame which displays the status of Berserk, Survival Instincts, Barkskin, Faerie Fire and Skull Bash
Cat Frame which displays Mangle( and Hemorhage/trauma), Rake, Rip (including glyph of shred support) on the current target as well as Savage Roar and Tiger's Fury. The timers on Rake and Rip disappear after the last tick, and go transparent when the debuff actually falls off.
Bear Frame which displays Mangle (including Berserk Proc), Pulverize(if talented), Lacerate, Maul, Swipe, Demoralizing Roar, Growl and Enrage
Proc frame which shows supported procs (and internal cooldowns when known)
Frames can be moved and disabled out of combat and per spec
Suggester Frame which shows the best* action to take, with projected future actions. If the current action is a combo point generating move, the top right icon will be the next action on a non-crit, and the bottom right will be the next action on a crit. If the current action is not a cp generating move, then the bottom will be the next action 1 GCD after the top action
Left side of the suggester frame shows charges/interrupts and cower when useable.

Suggester

Cat

The suggester frame is using a modified version of the Mew default script. There are probably some unintentional changes fromt eh mew script along with the intentional ones:

Latency is taken in to account in some places, but the support is a work in progress.
The window to use Ravage after a charge is larger
Savage Roar suggestion does take in to account combo points on dead enemies.
Any time Tiger's Fury is available and you don't have enough energy for the suggested move, it will suggest Tiger's Fury instead.
The timers on Rip/Rake count down to the last dot, but stay lit until the debuff falls off.

Bear

The bear suggester is pretty basic right now. The priority is FFF>Mangle>Thrash>Swipe>Laceratex3>Pulverize>Demoralizing Roar>Burn rage on lacerate.

Pulverize is only suggested if talented. Will show on the left side of the suggester frame if you have lacerate up and no pulverize buff.
Growl will be suggested if you are not tanking your target.
Demoralizing Roar is only suggested for boss targets and targets 3 or more levels higher than you.
Berserk proc is supported.
