    tdf#133026: Additions: Add Show More button and refactor
    
    After this patch, not all extensions that come with JSON will be shown. 
Instead, a certain number (currently 30) of extensions will be shown and the 
Show More button will appear after the last extension. If the user presses the 
button, a certain number of extensions will be added again.
