Task Management on opportunities and projects. It's so easy to use and fully keep track of how a project is progressing. I also like the features in the opportunity and project management space. The ease of converting an opportunity to a project is nice as well. I spend a good amount of time with the customer piece as well, utilizing notes as a way to track the various logins that I accumulate for customers. This way I can simply look and find information on the fly when a customer cannot find their information or when I need a quick login. I plan to use the sales funnel piece in 2018, but in this year it hasn't emerged as a requirement. That said, given the expansion I'm looking at in the new year, it only makes sense that I would dig deeper into the application so as to be better equipped for the new year without losing any time to do so.
