You can filter files (Document Manager > Documents > Edit View > Filters) in the DM log based on the E-Signature status. If all of the E-Signature features are enabled for the Company, Shell, and Project home landing pages, then the Edit View > Filters tab within the Document Manager log displays the E-Signature status as a field on the basis of which user can filter the records. You can filter on basis of multiple E-Signature statuses, and you can see the operators "equals" and "does not equal." The options are available at the end of all other fields, if configured, in uDesigner.
