100% agree, would be a GREAT feature to add a form field type of "People Picker" such that names can be chosen by the end user from a select list. Then when creating the field the admin can determine what group, team, or job role might populate the pick list. Ideall would support single or multi-select.
I have a use case now where we request a series of personnel to serve as contacts on a project when first created to aide with planning. right now the requester has to write this out long form where it is easy to fat finger something. Then the PM has to also add those people manually to the project.
