Gmail rolls out new pop-out window for composing emails

Google is , including a pop-out email-composition box rolling out today.

The new pop out box works like a chat box -- you can write more than one email at a time and minimize a message box if you want to finish the email later, according to a blog post by product manager Phil Sharp.

"How many times have you been writing an email and had to reference something in another message? Saving a draft, opening the old email, and then reopening your draft wastes valuable minutes. The new compose pops up in a window, just like chats (only larger)," Sharp writes.
