I've always had this idea in mind as a seller: Being able to receive notifications directly on our phones when we receive a private message or even alerts would (Push notifications for example), and maybe even be able to reply to pm's through the same App. I'm not an expert in mobile phone applications, but I suppose a mobile app in which you log in and where you receive immediate notifications once you receive a pm or an alert would greatly help sellers gain time to answer their clients.
