To view the main menu, you have to swipe down from the top bar (“Mailer” + “compose” icon). The menu with all the options unfolds and occupies the full screen, pushing the emails down.
To close the menu, swipe up (fold) or tap on any link of the menu. Or you can tap the “mailer” logo to be redirected to the inbox, closing the menu.
