Abstract: Systems and methods are provided for sending a combined read and reaction message. The systems and methods perform operations comprising: accessing, by a messaging application, a conversation session comprising a plurality of messages exchanged between a plurality of client devices, the messaging application being associated with a first client device of the plurality of client devices; generating, by the messaging application, metadata associated with one or more of the plurality of messages; encrypting, by the messaging application, the metadata in accordance with an end-to-end encryption process to enable a second client device of the plurality of client devices to read the metadata and prevent the second client device from modifying the metadata; and transmitting, to a server, a packet comprising an encrypted message slot and a first metadata slot, the first metadata slot comprising the encrypted metadata.

Abstract: A system to perform operations that include: causing display of a messaging interface at that comprises a plurality of messages; receiving an input that selects a message from among the plurality of messages, the message corresponding with a sender identifier; causing display of a menu element responsive to the input that selects the message, the menu element comprising a display of the message and a set of composition options; receiving a selection of a composition option from among the set of composition options; causing display of a text input field based on the selection of the composition option; receiving a text input via the text input field; and causing display of a quoted reply within the messaging interface, the quoted reply comprising at least the text input, the message, the sender identifier, and a user identifier associated with the user account.

Abstract: In some examples, a method includes maintaining first electronic contact data for a plurality of users of an interaction system, and relationship data relating to relationships between the plurality of users. The method also includes, using the first electronic contact data and the relationship data, automatically generating composite electronic contact data. The composite electronic contact data includes a first electronic contact record for a first user with which a specific user has a relationship as reflected in the relationship data, and a second electronic contact record for a second user with which the specific user has no relationship as reflected in the relationship data. The composite electronic contact data is presented within the interaction system in a manner that visually distinguishes between the first electronic contact record and the second electronic contact record. The specific user is enabled to initiate an electronic interaction with the second user.
