I use the Tablets "Future Blue" version for my mage, since it's very clean and has a dedicated pet window like the default UI, instead of sharing it with other info. It uses a new tab on the Actions window for extra info, and has a TON of modifications you can choose from.
Here's a link to it if you want to see what it's like:
