Currently, the message preview window is less wide then the email itself, which is very frustrating for previewing. It is usually less tall than the email, too. Please make the preview window adjustable so that we can enlarge it as much as possible so that we can better preview the entire message.
Seriously, this is very needed. The entire purpose of the preview view is to get a good look at your email so far. The small window—especially the width being less than the email itself—makes it very difficult to get a good look at it.
Yes please! This is still a problem for my team.
