After break stage is done either highlight NEXT btn as active or make PLAY btn start next stage

Firstly, want to thank you for your great app!

I've noticed one annoying issue: when break stage is completed, "Play" button highlighted as active, but clicking it does nothing. But I accidently click it anyway, because it's big, green and calls to action.

The solution would be probably to either make "Next" button bigger and active or make "Play" button start next stage instead of restarting current stage with zero time left, which is currently happening.
