I absolutely hate the new UI.  It's horrendously ugly, icons are even smaller  with text on the top which is unnecessary, the notifications are ten times worse, and a ton of other issues.  BUT MY MAIN ISSUE IS THAT WHEN I USE THE TIMER APP ON MY WATCH, IT REVERTS BACK TO THE WATCH FACE EVERY TIME I AM NOT DIRECTLY LOOKING AT IT.  I DON'T WANT IT TO GO BACK TO THE WATCH FACE, I JUST WANT TO BE ABLE TO SEE THE TIMER AS IT COUNTS DOWN INSTEAD OF HAVING TO SELECT THE SMALL ICON ON THE WATCH FACE.  THIS IS INFURIATING.  WHY WOULD I WANT THE APP I AM USING TO CONSTANTLY GO BACK TO THE WATCH FACE WHEN I AM USING IT?!?1!?!?!  I'D BREAK MY PHONE WITH A HAMMER IF IT DID THE SAME THING. NOW, I HAVE TO USE THE DUMB KNOCK FUNCTION OR THE DOUBLE BUTTON PRESS TO GET BACK TO IT AND EVEN THEN IT OFTEN GOES TO A DIFFERENT TIMER SCREEN.  I CAN'T SAY ENOUGH HOW MUCH I HATE THIS NEW UPDATE.
