How can I make "Pop out reply" the default behaviour to reply to an email in Gmail?

Question

I would like to make all my replies in Gmail "Pop out" replies such as shown in the screenshot below. Is this somehow possible?

Answer 1

I just learned that by holding down Shift while clicking the Reply button, you get the pop-out window you want.

Also, keyboard shortcuts let you easily open a pop-out menu for replies.
(If you haven't yet enabled Gmail keyboard shortcuts, click the Settings cogwheel, select Settings from the menu, scroll down to Keyboard shortcuts, and select Keyboard shortcuts on.)

With keyboard shortcuts enabled, when viewing a message in Gmail, pressing R opens the reply area below the message.
Instead of pressing R, press Shift+R, and the pop-out reply window appears instead.

Add the Auto Bcc for Gmail™ & Inbox™ extension. There is an option in the extension to auto pop out all replies.
