    It seems that a bug has slipped into the ToggleChildrenVisibilityRecursively method.
    Indeed, this method doesn't take into account the property AreChildrenVisible value of the connection target. So even if a shape is declared as collapsed, when a shape parent is expanded, this child shape is also expanded. Unfortunately, the togglebutton doesn't indicate this state.

    Below, a proposed solution :

    private void ToggleChildrenVisibilityRecursively(Visibility nextVisibility, IShape shape)
        foreach (var connection in this.ParentDiagram.GetOutgoingConnectionsForShape(shape))
            connection.Visibility = nextVisibility;
            if (!shape.Equals(connection.Target) && connection.Target != null)
                connection.Target.Visibility = nextVisibility;
                var l_mindshapeTarget = connection.Target as MindmapShapeBase;
                if (nextVisibility == System.Windows.Visibility.Visible && l_mindshapeTarget != null && !l_mindshapeTarget.AreChildrenVisible)
                this.ToggleChildrenVisibilityRecursively(nextVisibility, connection.Target);

    Keep up the good work
