Okay, it seems to me that the SDK3 update was succesfull, so i have just submitted it for review!

Coming up (i’ll first wait for the SDK to be released to live, then i’ll release this into test):  
The Pause/Resume and (now) start/stop buttons are pushable and the show the status:

And stopped:

**Now, you can push the start button when it is stopped, and the timer/transition/stopwatch will be started with the last started values.**

I’ll release this to Test as soon as SDK3 is live.
