This addon was made to show AP count in text, but many AP items of different values share the same name... so I was hoping someone could help me do 2 things with this addon...

#1 - remove the text altogether

#2 - have no fallback icon, instead if no AP items are found, display nothing, so the icon only appears if AP items are found...
