The original mod to this target window (1 minute timer added along with casting bar) was done by another author who I can not located at this time. (If the author will PM I will be sure to have this information updated to credit them.)
I added the pet bar to the window. This allows me to to keep my focus in one location when I have a charmed pet.
The top of the window is the target name with Hp's. At the bottom is the pet bar and in between is the casting bar. To the right is a one minute timer.
I placed this file under the Pet window mods only because pet owners would be interested in it.
