The control interface is operated by two seperate, but linked panels.
You can move these around the screen like any other UI element.
The first panel is above the skill bar.
This one indicates the hotkey assignments to issue "general commands" to your pets.
The second panel is in the upper left corner.
This panel controls the behavior of the pets you have active, setting their behavior modes and targets.
In order from left to right, Attack Target, Guard, Target Ally, Passive mode (no action).
Now that we have specific command functions in STO for ship pets, I would like to see control panels like this implemented to run them more easily during battle.
P.S: Look at the enemy NPC I'm targeting.
Does that name sound familiar?
