Add an indicator to desktop clock in/clock out button on upper right menu that lets you know a timer is currently running

When you add a timer from the desktop, there is no indicator that a timer is currently running once you close it to free up desktop space...you can't minimize either, just exit. This can lead to exiting Sage without clocking out, and the timer continues to run until you remember, possibly the next day, to clock out. It would be nice if the button for the timer changed color (or some other visible indicator) if one was running so you could always see it from the main screen.
