I, too, have suggestions.

While this application is simple and generally great for its intended use, there is one big flaw: it is far too easy to lose your time. The Reset and the "-" buttons are too easy to click accidentally, and there is no confirmation.

A simple confirmation ("Are you sure?") before resetting the clock or deleting the entire entry would be welcome improvements. Moving the reset button farther away from start-stop would also help, as would making the "-" button smaller.

The second problem is that this application does not behave in the expected OS X manner when closing the main window. When you click to close, the app shuts down, when instead it should remain running in the dock like standard Mac applications do.

Me, damnit. about iCheckClock
