Mark & Shane,
Until reading the docs for SD8 I had no idea the timer in the tool bar was a button. It is not obvious. People who read documentation would discover this is a button, but most people skip that and just skim the docs when they run into a problem.
It might be worth it to think if there is a way for that to be more obvious. Possibly something like a button that when clicked switches the display and is called a switch. Or the title underneath it says “timer/time broken down,” or something like that. Something that indicates it does 2 different things.
