The easy to use interface, which allows for seamless collaboration between team members in different time zones as well as across devices such as tablets or smartphones; it's also very simple (and free) to set up new users/groups within an organization so that they can access all of your projects at once! I wish there was more flexibility with how you could assign tasks from other teams who are not part of this specific group but rather just have general permission to view their assigned task list without having them be directly involved in said assignment process - however, since we're using klaru primarily internally, our internal customers do need direct involvement if needed by another department member outside of ours. This helps keep track of what needs done when and provides transparency into where work has been completed vs still outstanding items left over from previous deadlines etc.
