Walkthrough

A new callback for copying a sender's email address to the clipboard was added to the mail display component. The sender popover was enhanced with a larger avatar, improved layout, and a copy icon next to the email, which appears on hover and triggers the clipboard copy functionality.

Poem

In the mailbox where messages dwell,
A sender's email now copies well.
With a click on a bunny-bright icon,
The address hops to your clipboard, gone!
Avatars grow, layouts shine—
Rabbits rejoice in code divine.
