Add Unified Inbox to Rainloop webmail client

Hi, Looking for a talented programmer to add a unified inbox to the RainLoop Webmail client ([url removed, login to view]) RainLoop is a webmail client that allows you to use multiple IMAP/POP accounts at the same time, currently it does not have a Unified Inbox which shows all email accounts inbox emails in one merged inbox. If you do not understand what a unified inbox is do not apply for this job! Please go over the code before bidding as this is not an easy task.. Please write "candothis" in your bid so i know you've read this brief. US / CA / AU programmers preferred
