How do I set the default author for new SnapGene files?
Open Preferences
Click menu SnapGene → Preferences (macOS) or menu Edit → Preferences (Windows or Linux), and select "Files & Tabs" in the sidebar.
Use the drop-down menu to choose from a list of previously used author names, or type the author name into the "Author" field.
To avoid populating new files and collections with a default author, leave this field blank.

When you create a new file, the default "Author" entry will be added to the "Author" field in the file Info. See Hide or Show the Info panel By Default.
