IDEA #1
Basically its just like the player Level bar, cept its for your pet so u can see how much it has till its next level.
Once the pet hits level20 the bar will stay full, then u have the option to get rid of it via the edit interface menu.
Also the bar will only show if you have the Charm animal skill in your skill bar so it doesnt show when u havent got your pet or arent a ranger.
Screenie of what it could llook like:

IDEA #2
The second idea adds a new bar to your hero menu so it doesnt add more clutter to your HUD.

maybe being able to track your pets progression will open up a few new titles too, like pet survival maybe.
let me know what yall think.
