The interface is so dumb that users have to look up the functions INDIVIDUALLY themselves, in which those functions in other better Apps should pump up automatically upon launching and link up in sensible sequence. I wonder whether the big heads did walk through those steps like normal users who are new to this APP. Moreover how comes there is no information on where I can use the eTroll, as well as where this eTroll will be applied. I have to check this from other sources. That’s pathetic
