Have you ever been on a webpage that allows you to filter or limit what is displayed on that page? I bet that many of us create pages that are focused to specific interests or use Widgets to link to specific posts or groups of posts. Why not a filter or limit that allows the user to quickly limit the content of the website to what they are interested in?
For example it would be a widget that would refresh the page and display things sorted by a keyword, category or date. It would allow people to easily find information If the widget were popular, it might even be built in as a theme option.
On my site for example http://www.chimac.net I have people who only want to watch videos. However clicking on the Video category takes them to the WP site were all my videos are listed. There is no way to gather all the videos on one page that I am aware of, and people wouldn't know to search for Videos to find just videos. In addition there are some posts that mention video but don't have a video. By having this filter they could see that they could just see the multimedia types of a website like video, photos, audio without having to create manually built pages for it.
The blog I need help with is chimac.net.
