Quite good, needs greater versatility
I found it to be very good. But, I found that it needs changes to allow for a smaller display. If you have several countdowns set, it chews up a lot of screen real estate and begins to interfere with other open windows. A smaller window with sizable fonts would help. It would also be nice to have a single window with a columnar display of dates and times, at least when there are more than 3 or 4 countdowns.
