This is my biggest complaint as well. The new features of the UI are great, but it still looks pretty bad. There's a lot of white space and very little contrast between elements are groups of elements. The "Compose Mail" but just sort of hangs there awkwardly. The top row of action buttons are aligned to the left, so at higher resolutions there's just a chunk of whitespace to their right, even though the inbox itself fills the entire width of the container.
