This great PowerGUI Script Editor add-on by Gyorgy Nemesmagasi gives you the ability to browse PowerShell help topics right in the Script Editor (you can make the help window either float or be docked in the IDE) which makes it super-easy to lookup any PowerShell info when you need it:
The coolest part is that the add-on is loading all the information dynamically – so the cmdlet and alias list will depend on the actual set of snapins and modules you have, and the help information is in your language!
Very helpful and well worth checking out. Download the PowerShell Help Browser add-on here and make your PowerShell scripting experience even better! 🙂
