The Sugar theme is the original theme of version 1.0.  Although the Sugar theme is still available, it is no longer being enhanced to take advantage of new features, such as favorites.  The Sugar theme has the advantage of having all its key links always being visible. The number of items displayed in the Last Viewed panel is controlled by the setting name "history_max_viewed".

If the number of menu items exceeds the "max_tab" config value, the additional items are placed in the more popdown.
