Maybe it is just me, but I really don't like the updated (it happened a little while ago, I'm just now reaching the point of hating it) UI for setting a timer.
It used to be that you'd get a numeric pad of sorts and you'd enter the values that way. But now, it has changed to spinner dials for setting the numbers.
I have a harder time scrolling to the exact minutes/seconds that I want to set than when I could just type in the numbers and be done with it. This UI also takes me longer than just typing in the numbers. So, I prefer entering the numbers themselves vs. the spinner dials.
What's your preference?
