"CellDisplayCache"
• "CellDisplayCache" is an option for cells that determines if a bitmap representation of a graphics cell should be stored in a cache.
• With the default setting "CellDisplayCache" 
Automatic, a bitmap representation of a graphics cell is stored in a cache. This allows the cell to be rendered faster when you open the notebook or scroll through its contents.
• With the setting "CellDisplayCache" False, a bitmap representation of a graphics cell is not stored in a cache.
"DefaultCellGroupOpen"
• "DefaultCellGroupOpen" is an option for cells that determines if a cell group should always appear closed when a notebook is opened within the Help Browser.
• This option is only relevant for the display of cells in the Help Browser. When any information is displayed in the Help Browser, all cell groups are automatically opened, even if they were closed when the notebook was saved. This is because all cells have the setting DefaultCellGroupOpen True by default.
• You can, however, override this behavior and force a cell group to stay closed, by setting DefaultCellGroupOpen False for the leading cell in the cell group. This feature allows you to control the display of cells in the Help Browser, for example, to ensure that all heading cells for a certain topic are visible in one screen.
