As of 7.0, Blizzard seems to have lost the party pet bars on the stock UI. Toggling the check box in options doesn't help, unless you want to use raid frames.
If you want a stock UI, with pets (so you can heal them)... this mod is for you.
Warning... 1.0 is dead simple. It just sets the hidden value... then you need to reload your UI to get it to work. I decided not to make a popup window with a reload button because honestly, I don't think this will be needed for long. Blizzard SHOULD restore this function soon. I hope.
I also hope we'll get player housing and a dance studio... so... who knows.
If this continues to be a problem... I'll push the addon to 1.1 with a reload window.
