Add ability to have additional personal information fields for applicants. These ideally would be user-definable. For example, I'd like to have a field for "state" that shows which state the person lives in (eg. California). This would allow me to later on easily find all applicants that live in a given state.

(I suppose I could instead include a questionnaire question for that, but then how would I search "cleanly" -- without inadverdantly picking up other location names that might occur on applicants resumes, eg. where they attended school 7 years ago)
