In version 5.0.7, an option in the Settings panel lets users select their favorite browser (Safari or Chrome) for opening links in emails.
Users are now also able to select multiple messages in their inbox by tapping on the sender's profile image or icon next to the email, while messages can be marked as read or unread by selecting the email and tapping the 'open/closed envelope' icon in the top toolbar.
In addition, it's now possible to edit quoted content when replying to a message, and to copy and paste rich text content in a message.
