Google has introduced a redesigned Gmail composer which will make it easier to refer old e-mails while composing new ones.

Gmail product manager Phil Sharp said that 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 said.

Google has also added some other new features to the compose experience such as the ability to insert inline images in a message on which the user is working.

Sharp said said that users will also be able to drag and drop the new address chips between to:, cc: and bcc:, and when the addressing is completed, the address area collapses automatically to get out of the way.

Google, which rolled out a preview of new composer this week, said it will launch the new format for everyone over the coming months.

In August this year, Google had revealed that it will be trialling a feature that lets users see results from their Gmail inbox when searching the web.

Earlier this month, Iran had lifted ban on the secure-protocol HTTPS version of Google search and Gmail service, while its video-sharing site YouTube still remains barred since 2009.
