I like that this software allows me to create tasks in order of priority as well as track my time spent working each task with dates/times associated with it.
It's easy enough so anyone who has basic computer skills should have no problem using it! Nothing really at all since we use their services through our agency but they are always responsive when you need them too which makes things easier than if there was more distance between us (we're located out-of state). They also provide great customer service by phone or email whenever needed even though sometimes emails don't come right away from some people due to internet issues etc., especially during busy times such as holidays where everyone gets behind schedule because of how many clients call asking questions about what needs done next - not fun :P.
