New Custom Fields to Show Create Date and Description

When creating a new custom field in Marketo, it would be really helpful if a description box was provided below the field name. This would allow for the addition of notes during the field creation process that could be referenced whenever that field was selected in the Field Management. Then, we could better understand the history for why a field was created. It would also be great to have a timestamp whenever that field is created to know how old or new a field is.
