This PowerPack by DJ Grijalva gives you UI for the functionality missing (or really hard to find) in native SharePoint Central Admin, including diagnostics and management for search, applications, accounts, sites and subscriptions.
You no longer have to go to command-line to perform these management tasks, but that is not it – because it is a PowerPack:
- Bulk update: All actions support multiselect – so you can update multiple sites or other objects – you just select them all and click the action,
- Learn to automate: You can see the PowerShell script behind everything the the tool does – just see properties for any UI element or go to View / PowerShell Script menu item,
- Extend: Add your own nodes and actions using the PowerShell cmdlets shipped with SharePoint 2010.
