Yeah I know I should finally add them in, lol. When I originally put them in I still thought they'd only show up when someone is speaking, but since they are always visible I hid them again.
If you want to turn them on you need to remove the visible="false" from those lines. But you'll also need to change the icon style to whatever the defaultUI uses, because the custom graphic I had made and which the ProfitUI_Styles is pointing to does in fact not exist in the released skins because I forgot to update my script that is generating them when I did them. Yeah...
Also: Clicking on them to bring up the voice menu does not work for many characters on international server because EQ2 UI scripting does not support international characters. There, I said it again. The only UI bug worth fixing and they won't touch it.
