I have been using PowerShell Plus for my PowerShell IDE. It is not free but I really think that it is the best IDE for PowerShell. They released version 3.0 not to long ago and it is even better. Along with the great code editor, debugger, and interactive window, they have added a learning center, and a nice little quick click library. this library is a side bar on the interactive Console that has some simple one liners that come in handy. Just click it to run it. They have them broken down into groups like computer managment, Printer managment, and Network Management just to name a few. Please check it out and support a great product. Try out the 30 day trial at least.
