By incorporating a smaller design, Today Widget could be greatly improved, especially on devices that have smaller screens.
Using the widget to quickly see what's left for the day is much faster than launching the app (iPhone 6). On a busy day, current cards don't fit on the screen(ss.1), and I think they look a little too big. And "Show Less" (see ss.2) also fails to give me an overview at a quick glance. I think the general design works for the app, but it's a little clunky for the Widget.
I kinda like what Up Next does with the Reminders (ss2) in the minimized view.
