This CodePlex project provides custom workflow activities for SharePoint Designer.

LINQ to SharePoint
Bart De Smet is working on a tool for using LINQ with SharePoint.

U2UPropertyPagePackage - a feature that adds a List settings page
If you ever needed to get all the details on a list including the ID, properties, content types, site column IDs, and more this feature is for you.

Application Pool Recycle Utility for SharePoint Developers
System Tray utility shows you all the application pools for your IIS and allows you to recycle them via the click of a button.

Updates to resources:

SharePoint Solution Installer: the source code for this tool has now been released via CodePlex.
