What a difference a year makes and this is particularly true when reviewing the development that has been occurring for the Joomla! CMS over the last 12 months and, in particular, the emergence of some amazing Javascript/AJAX technologies that are starting to make a big difference to the way your site visitors can experience and navigate through your website.

An example of some fantastic, emerging technologies can be found at YOOtools, where the developers have created an array of amazing extensions that can enhance the way your website visitors navigate through your site and provide you with flexible ways of re-using the same browser 'real estate'. These developments include:

• YOOcarousel, which shows a category of articles and creates a slide or fade transition when cycling through the articles;
  
  
• YOOaccordian, which displays a collection of articles and creates an accordion effect with smooth sliding when selecting an article;
  
  
• YOOslider, which can be vertically or horizontally aligned and comes with a nice sliding effect while hovering over the individual items. When you hover over a slider item with your mouse, the item will expand to show additional information and on 'mouse-off' the item will shrink again.
  
  
• YOOtoppanel, which can provide a hidden module or content item, commonly placed at the top of your website/template.
