I saw an MSDN Forum post today, so I looked for a ListInstance Hidden property in SharePoint 2007 features. There is none, but interestingly enough there is one in 2010. I wondered what would happen if you did this: <Elements xmlns="http://schemas.micro... <ListInstance FeatureId="00bfea71-de22-43... Title="Hidden List Test" Description="Testing a hidden list." TemplateType="100" Hidden="TRUE" OnQuickLaunch="FALSE" Url="Lists/TestHidden" /> </Elements>...
