SharePoint 2010 gentelman's tool set (freeware)

I have compiled a tool set for SharePoint 2007 a time go which can help developers to handle SharePoint 2007 issues easily. All mentioned tools are freeware.

I am starting compiling tools for SharePoint 2010:

SharePoint Feature Administration and Clean Up Tool - http://featureadmin.codeplex.com/ - helps to investigate missing features and remove them. The most common task after database attach upgrade is to get rid of 367b94a9-4a15-42ba-b4a2-32420363e018 ReportServer SharePoint 2007 feature. Feature Admin Tool v2.2. makes is fast and easy!

As before, a tremendous help with reading SharePoint logs -ULS Viewer - http://code.msdn.microsoft.com/ULSViewer - ULSViewer allows users to open a ULS log file and display its contents in a user friendly format.

A descendant of The SharePoint Manager 2007 -  http://spm.codeplex.com/  SharePoint manager 2010- still powerful  and "must have" for everybody who touches the SharePoint from administrative side.

A great tool to diagnose farm performance by MS - SPDiag 3.0
