Google is rolling out a new design for Gmail over the next few days. It
features more white space, less clutter, threaded conversations, new
themes
and better search.
Messages aren’t as bunched up as before and easier to read. Adding a
social element, Google is adding profile pictures beside each message,
and the labels pop out more. The density of the text also adjusts
depending on your screen size and resolution, making it easier on the
eyes. The new design is in line with some of the changes Google just made to Google Reader in terms of spacing and overall feel.
