The app has a large list divided into header categories like Sad, Cute, etc. There are a lot to choose from. But for 90% of these I have no idea what they are or mean. For me this app isn’t useful at all because I’m not already an expert in these emoticons. What is needed is either a definition or a vector graphic showing what each emoticon means and/or represents, in a crystal clear way. I’m sure it would be some work but it would really increase the usefulness of the app.
