Pros Lets you name the clocks Drops from the bar Can be system so no open app on Doc Bar Some visual styles to choose from. Cons Interface can be confusing when trying to name the clocks but stick with it. Map view for loacting time zones is cumbersome to move around in. Names of places appear in clock name in a way that overwrites my typing and had to renenter a clock several times. No way to modify a clock name, have to delte it and start over.
