Systems and methods for displaying electronic messages are disclosed. In some implementations, a method includes, at a computing device, displaying a user interface for a messaging application, comprising an electronic message list. The message list comprises a plurality of objects. Each respective object in the plurality of objects is visually distinct in the message list and represents one or more corresponding electronic messages. The method includes detecting user selection of an object in the message list and in response to detecting user selection of the object, toggling display of the first object from a first state to a second state. The method includes moving a first subset of objects vertically upward, where the first subset of objects comprises one or more objects above the selected object, and moving a second subset of objects vertically downward, where the second subset of objects comprises one or more objects below the selected object.
