Kirk has posted a fascinating PowerPack to the PowerGUI.org library – Integrated PowerShell Help (click the picture to enlarge it):
Basicall, it give you GUI console to slice and dice the help system – both from the native cmdlets and whatever 3rd-party snapins you got installed. You can sort, use filter for search, or just browse around to see what’s there.
Links and Actions let you open full articles, examples, and syntax descriptions, explore various dependencies and related items. Very handy!
It shows you various groupings as well. So you can see, for example, that in the native set the most popular verb is Get- (29 of those) and the most popular nouns are -Item and -Object (9 cmdlets each).
Looks like a very handy tool for studying and using PowerShell!
