+
 Version 2.2.0 provides the ability to turn on/off the file list (default is on)
 
 Version 2.1.0 now provides a much easier way to configure some options, be it the poll time, toggling the ability to reset the cache, real-time updates, etc. It also allows you to show the big values (memory usage and hit rate) as gauge graphs instead of big numbers.
