Turning off the Layouts tab

Hi,

I dont like to have Layouts Tab (Model, Layout1, Layout2,...) on bottom left side of AutoCad and I prefer to hide it.

Is there any system variable for that purpose?

I just hide it via lisp only:

(vlax-put-property (vlax-get-property (vlax-get-property (vlax-get-acad-object) 'Preferences) 'Display) 'DisplayLayoutTabs 0)

 Thanks
