We've added the below new Meta Data fields that are available in the Form Builder, the Workflow Builder, and in the Document List when creating reports:

• Last Modified By - The user that last modified the document. You can also pull the ID, Display Name, School ID, Email, and Username information associated with the Last Modified By user. 
• Last Modified At - The date the document was last modified.  Please note, the Last Modified At field for prior documents will show as 'Not available' until the document is modified.
• Workflow Runtime (From Submission) - Lists the amount of time a proposal has been in workflow after initial submission.  This value will populate once the workflow is completed for the document (statuses of Complete, Denied, and Withdrawn). Please note, in the export it will show the total amount of time it's been in progress in milliseconds.
• Workflow Completed At - Displays the date the proposal completed the workflow.

More information can be found in the Meta Data Fields article.
