Idera has just released a beta of their latest version of PowerShell Plus, which you can download now from http://www.idera.com/Products/PowerShell/.
PS+ is a scripting GUI aimed to help both admins and developers make the best of PowerShell. PS+ has an interactive console, an advanced script editor and a comprehensive learning centre. For those that know it, PowerShellPlus Professional Edition is built on the backbone of PowerShell IDE.
The beta edition is currently free but the final version will be commercial. Idera are offering a good discount on the final version to beta testers. This looks to be a nice product (and I’m using it already!)
