Abstract: An electronic device: displays an inbox view of a messaging application that includes one or more groups of electronic communications presented in a condensed mode, wherein a first group of electronic communications in the inbox view includes a first plurality of messages with at least one different subject and from a plurality of unrelated senders that are associated with a common characteristic; detects a first user input selecting an expansion affordance associated with the first group of electronic communications while in the condensed mode; and, in response to detecting the user input selecting the expansion affordance associated with the first group of electronic communications while in the condensed mode, the first group of electronic communications in an expanded view different from the condensed mode that includes at least some of the first plurality of messages associated with the first group of electronic communication.

Abstract: An electronic device: displays a plurality of representations of electronic communications associated with a first grouping and a filter affordance that corresponds to a set of filter criteria; and detects a selection input selecting the filter affordance. In response to detecting the selection input, and in accordance with a determination that the selection input corresponds to a first input type, the electronic device: ceases to display a first set of representations of electronic communications from the first grouping that do not match the set of one or more filter criteria; displays a second set of representations of electronic communications from the first grouping that match the set of one or more filter criteria; and displays an indication of the set of filter criteria that have been applied to the electronic communications associated with the first grouping.

Abstract: An electronic device: displays a conversation view of a plurality of messages within a first pane of a messaging application, where the conversation view includes a first message region of a portion of a first message and a second message region of a portion of a second message; and detects a user input selecting the first message region within the conversation view. In response to detecting the user input selecting the first message region, and in accordance with a determination that the user input satisfies first input criteria, the device displays one or more affordances provided to perform corresponding actions on the first message. In response to detecting the user input selecting the first message region, and in accordance with a determination that the user input satisfies second input criteria, the device replaces display of the conversation view with a message view that corresponds to the first message.
