I like rounded buttons. I prefer a bit of empty space over having a cluttered UI filled with buttons I'll never use. I like animations. The problems with such UI overhauls is usually that the changes overshoot the target by a mile and the designers seem to focus more on visual design than usability. Animations are almost always too long, because their purpose - for example signalling that it has registered the input - is forgotten. At this point at least web apps should just offer options to completely configure the UI layout with a JSON or HTML file and CSS.
