Jexus Manager for IIS Express is a management console that's quite similar to IIS Manager,

Unlike command line access (IIS Express's appcmd), or a small set of settings to change (like other IIS Express utilities or Visual Studio/WebMatrix), Jexus Manager is designed to provide access to as many settings as possible (even more than IIS Manager if technically feasible).
