Electronic device and method for selectively applying message actions

An electronic device, comprising:

• a display interface;
• a processor in communication with the display interface, the processor being configured to:
• display, on the display interface, a message thread listing view comprising a listing of message threads, each message thread comprising a plurality of email messages;
• while the message thread listing view is displayed, detect a selection of one of the message threads from the listing of message threads;
• concurrently display a menu overlaying the message thread listing view and a highlighted box representation of the selected message thread, the menu including one or more user interface elements associated with single-message actions applicable to messages of the selected message thread, wherein the single-message actions include at least a reply-to-all action;
• detect a selection of a first user interface element that is associated with the reply-to-all action while the selected message thread is displayed in the highlighted box representation;
• and
• in response to detecting the selections of the message thread and the first user interface element:
• automatically identify a first email message from the selected message thread for applying the reply-to-all message based on:
• automatically identifying a subset of the messages from the selected message thread, the subset including only those messages that have multiple recipients;
• and
• selecting one of the messages in the subset that is the most recently received message among messages of the subset and that is different from a most recently received message of the selected message thread that does not have multiple recipients, and
• replace the message thread listing view with a message composition view for composing a reply-to-all message, wherein an address field of the reply-to-all message is pre-populated using addresses from the identified first message.
