    Demo Browser
    
    Makes using the Demo Programs each even more powerful.
    Now you can quickly filter and search to find the demo you need.
    You can launch editing the demo using your favorite editor.
    
    On first run, click settings button to enter location of your demo programs.
    
    Filter the list of demos using:
        * Search using filename
        * Searching within the demo program's source code (like grep)
    
    The basic file operations are
        * Edit a file in your editor
        * Run a file
        * Filter file list
        * Search in files
    
    Additional operations
        * Edit this file in editor
