Several questions around set up and integration - please help

- ho to you easily move from inbox in mail to reach the docs? I have clicked on the icon next to the logo in the top left corner and clicked docs but it then navigated to a new tab with a sales page, it didn't carry my login over.

- can you view more than one inbox and switch between views? I have my own name@domain.com but I also want to see directors@domain.com without needing to log out and then in again?
