How to show in the VB6 IDE in tabs, open project forms

How to show in the VB6 IDE in tabs, the open forms of the project? In Delphi it already shows everyone, but in VB6 I do not know, I've never seen VB6, it's the first time. How to close open forms? This is in design time, not run time. It is not closing in the Application, but in the Project (vbp), because I open the More Window window and there is a lot of form open and I can not close.
