Fizzwidget Hunter's Helper (2.4.3)

Really, I'm not one to gallivant about the wilderness trying to make friends with beasts... at my size, it's a good way to get eaten! Besides, keeping a full stock of bits & bibbles for your critter can be terrible for your cash flow. But a Hunter friend of mine managed to convince me there'd be good money in outfitting such outdoorsy types, and before I knew it my workbench was cluttered with all sorts of animal-seeking, food-measuring, and pet-minding contraptions.

This gadget couldn't be any simpler to use: point it at a beast you see in the wild, and its zootropic neurowave scanner will analyze the critter's noggin and tell you what, if any, new tricks it can teach you.* Know what you're looking for, but not sure where to look? It'll help with that, too -- I've pre-programmed it with an extensive database on creature behavior (straight from Petopia (http://petopia.brashendeavors.net), the best zoological resource on Azeroth), easily indexed by skill.

* Not recommended for use by elderly gnolls.

Features

When you mouse over a beast in the world, the tooltip will show which abilities a Hunter could learn after taming it. (Or no additional info if the beast doesn't have any known abilities.)
If you're currently playing a hunter, the abilities will be colored according to whether you've already learned them: green for abilities you have yet to learn, and gray for those you already know.
Need to know where to find new abilities for your pet?
Type `/huntershelper` (or `/hh`) to show the Hunter's Helper UI and browse its database by ability or by zone. Various filters and a search feature are available, so it's quick to find a pet that has what you're looking for.
Visit the Hunter's Helper pane in the Interface Options window (or type `/hh button`) to enable the HH minimap button, which shows when you're in a zone that contains beasts you can tame to learn new abilities. (Mouse over it for details on them.)
Type `/hh find ` for a quick search with results in the chat window.
The Hunter's Helper UI also serves as an improved replacement for the Beast Training window; its compact layout and flexible filters make finding an ability and rank much quicker... and it shows accurate training point costs for upgrading an ability to a higher rank. (Tip: this means you can also show the HH UI by "casting" Beast Training from your spellbook, action bar, or macro.)
Hunter's Helper also notifies you in chat if you tame (or cast Beast Lore on) a beast whose skillset isn't what was expected. HH's database of pet abilities comes from Petopia (http://petopia.brashendeavors.net) -- visit there to submit a correction.
