The SharePoint User's Toolkit is currently under construction. Expect to see more Web Part builders and documentation in the weeks to come.
If you have an issue with one of the scripts, or want to suggest enhancements, please send me an e-mail. I usually respond within 24 hours.
If you have a specific need that is not covered by the current free tools, check out the list of upcoming online workshops or register for a one-on-one session on the Path to SharePoint home page.
If you are a SharePoint consultant and would be interested in a custom copy of the SharePoint User's Toolkit, feel free to contact me to start a collaboration!
