Microsoft SharePoint Administration Toolkit
The SharePoint product team has released the first version of the Microsoft SharePoint Administration Toolkit which is supported on MOSS and WSS. I was surprised that it didn't have that many initial tools- but the ones it does have are super sweet. I think the feature that is going to be welcomed most by SharePoint admins is the ability to move a site collection to a new content database. There are promises of future and regular releases so I can't wait to see what they add next.

Some tools I'd personally like to see in future releases (and to stay with the site collection theme here):
- Manage multiple site collection themes - all or those selected at once (would just be nice to do this from CA instead of having to go to each site collection)
- Manage quota templates for multiple site collections - all or those selected at once
