• in response to a selection, from a first user, of a selectable element in the hierarchical element tree, causing a document to be displayed in the content panel in a synchronous editing mode in which:
• the document is editable by the first user and a second user;
• edits from the first user are visible, in real time, to the second user;
• and
• edits from the second user are visible, in real time, to the first user;
• in response to receiving, from the first user, a request to edit the document in the publication-controlled editing mode, causing the document to be displayed in the content panel in the publication-controlled editing mode in which:

• and
• in response to receiving the publication request from the first user, the edits from the first user are visible to the second user.

A computer system comprising:

• at least one processor;
• and
• at least one memory storing instructions, which when executed by the at least one processor, cause the at least one processor to perform operations comprising:
• causing a client computer to display a graphical user interface including:
• a content panel configured to display a selected document in a publication-controlled editing mode and in a synchronous editing mode;
• and
• a navigational panel including a hierarchical element tree, the hierarchical element tree comprising a plurality of hierarchically arranged selectable elements, each respective selectable element being selectable to cause display of a respective document associated with the respective selectable element in the content panel;
• in response to a selection, from a first user, of a selectable element in the hierarchical element tree, causing a document to be displayed in the content panel in the synchronous editing mode;
• while the document is displayed in the content panel in the synchronous editing mode and in response to receiving, from the first user, a first edit to the document, causing the document with the first edit to be displayed, in real time, to a second user;
• and
• in response to receiving, from the first user, a request to edit the document in the publication-controlled editing mode, causing the document to be displayed in the content panel in the publication-controlled editing mode;
• and
• while the document is displayed in the content panel in the publication-controlled editing mode:
• receiving, from the first user, a second edit to the document;
• and
• causing the document to be displayed to the second user without the second edit.
