limit to single content type

Issue Summary

If, in situations where you may have multiple content types that you need to order, when set to show title only it might be difficult to differentiate the types. Perhaps you could allow nodeorder to show content type as well as title?

An alternative to above would be to allow nodeorder to only show certain content types by selection. So, for a given taxonomy term, the user could set up nodeorder to only show a specific content type in relation to the term.
