my thoughts on the email design: - Comparison is strange. One email has an image, the other text. Not the same email. - Hiding the previous parts of the thread seem good by default, but how do you easily get them back? - Where is "from" in new design? - Where is "to" in new design? - I do like expanding attachment a bit so you don't have to click twice to attach a photo (for example), but I'm not sure how often some of those options are used, may be too much. I could see a photo icon and general attach icon both showing. - Back arrow looks broken in new design.
