Copy the sponsor field to child tickets in trac.ini
Like #22988 (moved), we want the sponsor field to be copied to child tickets created using the "New Child Ticket" button.
So we'd like trac.ini to have:
parent.enhancement.inherit = cc, version, keywords, component, milestone, sponsor
parent.task.inherit= cc, version, keywords, component, milestone, sponsor
parent.project.inherit = cc, version, keywords, component, milestone, sponsor
parent.defect.inherit = cc, version, keywords, component, milestone, sponsor
To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
