"Move to junk and blacklist domain" as 1-click button

Hello, I receive a lot of spam e-mails daily. It would be very convenient to have a 1-click button in the main toolbar to move e-mails to junk and blacklist their domains.

Right click on the Toolbar and click Customise and add the “Move to Junk” button. You click then do a one click move to junk and blacklist domain in the dropdown.
