Spotlight: PowerShell Plus
Touted as the most advanced IDE for the PowerShell scripting language today, PowerShell Plus is free and offers an advantage over generic software such as Eclipse, as it is purpose-built. The software application is easy to setup, and offers a standard interface that adheres to standard Windows guidelines--including a ribbon bar. As you may expect, multiple tabs can be opened in the main window with their own set of configured controls. PowerShell Plus also supports several source control systems for team development, such as Visual SourceSafe and Team Foundation Server.
