I've been looking for an app with this functionality for FAR too long. I've found others that use large ugly clocks, a candidate that required code for alternate time zones, or ones that don't work with the date/time pref; but this is 97% of what I'd make (if I weren't too lazy to program). Why only 97%?

1%: I wish i could have my menubar clock a simple time only read-out (or small clock icon) and the four additional time zones could show date and am/pm. I know the day HERE, but the Intl Date Line always messes with my pea-brain. My menubar needs an icon reduced diet.

1%: I wish I could view a calendar or open iCal by clicking on the pull-down's date.

1%: I wish I could relocate the menubar clock by option-click drag or cmd-click drag.

Oh ya, and I wish the author the best for a great app.
