Abstract: Various embodiments of the present invention are directed to an improved group-based communication apparatus that is configured to manage draft messaging communications and various interfaces associated with such draft messaging communications in a group-based communication system. The group-based communication apparatus is configured to render a draft message composer interface to a group-based communication interface to provide an interface for a user to compose a draft messaging communication, including indicating a destination and/or content to be included in such draft messaging communication. The group-based communication apparatus is further configured to detect engagement of interface components and assign draft message titles to draft messaging communications. The assigned draft message titles, or draft message placeholders when no draft message title is assigned, may be displayed to a sidebar pane of the group-based communication interface.
