Re: Smilies Emoticons Emojis whatever
Reply #3 –
"Sets" are meant to be alternative smiley that the user can select, pretty much the equivalent of a different theme.
To add new smiley, yes, you have to add them one by one (anyway you have to specify the code one by one, so...).
The emoji addon looks like has something to do with the url set, maybe @Spuds has an idea?
