Flow names and flow titles
Whenever you add a flow to a project, the default name of a flow is Flow plus an incremental number. You can rename flows in the Project Info dialog and in the Flows panel in Setup mode.
When you enter names for flows in the Flows panel in Setup mode, those names are automatically added in the Title field for the appropriate flow in the Project Info dialog. If you change the name in the Flows panel again later, the flow title is updated in the Project Info dialog.
Titles shown in scores and parts in the music area are linked to the Title field for each flow in the Project Info dialog.
This link is maintained until you change the names of flows in the Project Info dialog. Once you change flow titles in the Project Info dialog, changing flow names in the Flows panel no longer updates the Title field for that flow in the Project Info dialog.
This allows you to organize flows in Setup mode with different names to their official title.
