After Gmail's new compose rolled out to everyone in March, many of you sent us requests for features you'd like to see added. We listened carefully to your feedback and as as result, the new compose now offers a full-screen option.
When this option is enabled, the compose window is centered in your inbox and expands to fit on your screen. In addition, the formatting toolbar is on by default. You can click on the expand button in the top right to switch to full-screen or set full-screen as the default by selecting Default to full-screen in the more options menu in the bottom right.
The full-screen option is rolling out to everyone over the next couple of days.
