Though we don’t have intentions to carry developing PowerShell Analyzer much in the future, there are a number of improvements in my personal fork, and we want to make sure that it keeps its shelf life by updating it for PowerShell V2. Surprisingly we are still getting hundreds of downloads a day so we want to make sure that those who prefer PSA can still keep using it and also take advantage of the features I use day in and day out. We’ll probably release some new builds within the next couple of weeks, but will post some screenshots and maybe videos until then. We hope that will minimal effort keep PSA the best free PowerShell tool. However if want a tool that is definitely worth paying for check out PowerShell Plus at its new home at Idera - http://www.idera.com/Products/PowerShell/
So here is a screenshot of PowerShell Analyzer running with PowerShell V2 CTP3. The new features are all related to the help features of advanced Functions.
- Region support for multiline comments <# #>
- Syntax Coloring for help documenting keywords (i.e. .DESCRIPTION )
- Code Completion for help documenting keywords.
- Rich Rendering of advanced function help from get-help in HTML (any advanced function that is in the RunSpace)

So there. you go. However the help rendering is only in our really old 3 year old Help rendering engine. If you like it wait for our HelpFusion app which will be separate and be able to be used independently or from any PowerShell host. Some of you have seen it, but the rest of you will have to wait until we finish rewriting it for WPF.
