Currently using Prat 3.0 version 3.3.19 before posting what I posted yesterday. I had come here first to find if someone had made the request, because the emote button had completely disappeared in 3.3.18 for me, but I had not played the game after updating from 18 to 19. So it was not until after I logged in the game to find that the button had 'returned'.
However I did noticed some folks mentioning they wanted the emote button hidden. Me personally, I like using emotes. Thus why I thought to suggest a check box to hide/show it like you have with the arrow buttons. *smiles*
Thanks for the swift response.
