Examples: Limit categories to single row and allow showing all

Browse Source 
Limit the items shown for categories to a single row (two rows for first,
"featured" category), and add a "Show All" link/button in the heading,
that shows all items in that category only (with a "Back" button).

The "Search in Examples" input ignores categories.
