It has been a few days since Google rolled out the new Gmail tabbed interface. Many have been in the favor while many don’t like the newly introduced interface. Recently, Google announced that it will roll out a new full screen compose window for Gmail. Previously, when you compose a new email, a small popup window appears that resides in the bottom right corner of the screen. You can click on the popup button to use it as a separate window but many users prefer to work in the same tab with a full screen compose windows, as it gives them more room to write emails.
