It has made our work much easier to complete as it helps us to manage all of these docs in one place so we don't need multiple applications or software for that matter! The interface seems simple enough but there are some things I find confusing such as moving through folders too quickly when you want to pick up where your last task left off (I'm looking at my emails right now).
But other than those minor issues this program helped me organize my documents better which was very beneficial especially if working remotely because then no longer do i have access to papers scattered around my desk since they were stored online.
