Open Subproject Individually
This command opens subprojects of the current project in separate tabs of MobileTogether Designer. On hovering over this command, a submenu rolls out that contains a list of the subprojects of the current project. In this submenu, select the subproject you want to open. If no subproject exists, then no submenu rolls out.
Subprojects of the current project are listed in the latter's Files Pane.
