Unzip "eq2ui_mainhud_pet_commands.xml" and place in your UI mod folder.

In your UI mod folder, edit the file called "eq2ui_mainhud.xml" to add the following line:

 <include>eq2ui_mainhud_pet_commands.xml</include> 

Start EQ2 and type the following (or create a macro containing this line):

/show_window MainHud.PetCommands

This new window can be moved if you carefully place your cursor right in the top left corner.


Also included is Mook's original pet window, if you also want to just have the pet health and power all on it's own, just unzip "eq2ui_mainhud_pet.xml" and place into your UI mod folder.
In EQ2, right-click on the new pet window and select "window settings" and choose "none" for frames. You should be left with just the pet's health and power window so you can place it discretely out of the way, but within easy eyesight.
