Is it possible to open Synopsis, General, Custom Meta-Deta, AND Notes in the Inspector at one time?
No; custom meta-data is in a separate tab from notes, so it’s one or the other there. You could open the same document in a QuickReference window and view the document notes/custom meta-data there or split the editor and view the outliner with the meta-data displayed in one in order to see everything simultaneously. Or if you’re after project notes rather than document notes, you can open those in their own window from the Project menu.
Thanks very much. This is exactly what I needed to know!
