I finally addressed the multiple stations running issue with the status bar in the header, @djagerif.
Now, if multiple stations are running at the same time it will instead show the count of stations running and then show the program total duration countdown.
At the very least you now know more than one station is running and you get the program total. Going to hopefully incorporate the program total into the current status page as well but leaving that for the weekend.
