 *  -Online peers
 *  -Queue history
 *  -Execution Logs
 *  -Queue settings
 *  
 *  -Managing task groups and order
 *  -Managing task folders and order

 *  -Managing peers and association with tasks
 *  -Enabling/Disabling peers
 *  
 *  -Rendering scheduler related reports
 *  
 *  Changing anything in this class required extensive testing as it can directly impact the queue behaviours and sometimes may lead to
