The ease of use for all my colleagues who are new at this software as it was very simple with no learning curve required!The ability in creating tasks which can be used by others without having them log into their own accounts makes our work easier than ever before when collaborating across departments or countries within an organization!! I would love if we could create more custom fields so that there will always remain some room left open up from time-to timewhen adding information via email attachments etc., but otherwise everything works great already.
