The free tool SharePoint Manager 2010 is super useful. Imagine a centralized place to look at everything on the server level from Content Type usage to running jobs and IIS setting. Check it:
I found it after looking for a non-PowerShell solution to solve the whole “Content Type in Use” issue. The only feature I’d add, really, is to allow me to connect to remote servers. I’m currently developing on a super locked-down site and this actually didn’t solve my issue — nor could it, really. I’m only a Site Collection admin on this farm and wouldn’t have permissions to see any of this. Boo hiss.
