User interfaces for navigating structured content

A non-transitory computer-readable medium storing an application configured to cause a computing device to generate a user interface on a display device associated with the computing device, the user interface comprising:

• a two-dimensional grid having a single level of rows and columns;
• a header row of header row cells each positioned in a separate column of the grid;
• a header column of header column cells each positioned in a separate row of the grid;
• multiple cells of structured content, the structured content of each of the cells belonging to a specific one of the header row cells and a specific one of the header column cells which results in the cell belonging to only a single intersection position in the grid which represents the intersection of the column of the specific one of the header row cells and the row of the specific one of the header column cells;
• and
• a cluster cell belonging to only a single unique position in the grid, the cluster cell being configured to:
• represent a set of two or more of the multiple cells which all belong to a single unique intersection position that is identical to the single unique position of the cluster cell in the grid;
• before selection, display the cluster cell with displayed representations of the structured content of the set of two or more of the multiple cells;
• and
• after selection, display the set of two or more of the multiple cells.
