Well I can Drag the Display Screen to the Left and Dock it and move the Project Media to the Right.

And I can not Un Dock the TimeLine and I did look for it in the Menus Option to Un Check it.

Please see my screenshots. Click to enlarge.

3 images of my Pro layout ( for Platinum and Vegas )

as you can imagine , this layout is really good for compositing Parent\Child tracks . I need that Vertical Stack

I would post a pic of the layout , if I could .

The layout is made of 5 floaters .

The Layout works on a 1080  res. TV\monitor

( Left )    ( Right )
( side )    ( side  )

Time Line | Viewer + Scopes
Time Line | Time Code Stamp
Time Line | Device Explorer
Time Line | main interface windows + Surround Panner + 5.1 Level Meters

( there is No vertical   gap )
( there is No horizontal gap )

the above is a rough look of how i do it ,
Any version of  Vegas Movie Studio Platinum and
any Vegas Pro can be setup that way .

the Left side Top to Bottom is the Time Line .
Full Height at  Half width .
Time Line is in it's own dock , by itself .
The entire time line thus is a floating window ,
positioned and sized , on the left side of the TV\monitor .

The Viewer sits in it's own dock ,
as a floating window , positioned and sized
at the Top Right  quadrant of the TV\monitor .
Sized to about 50% wide by 50% Tall .

Scopes window is docked on top
of the View window . Scope window is docked as a
"Slider" .  When NOT using Scopes , Scope's window is
slid to the right , to  "close" the scopes windows ,
which reveals the full size of the top right quadrant View window .
When using the  Scopes , slide scopes toward the Left .
Doing this will make the View window to become smaller ,
while the Scopes become Full size in the  upper Right quadrant .
i do not need to see a large  Video View , when viewing the scopes .

The  Time code stamp sits in it's own dock ,
just below the  Viewer .  As a floating window .
( i get a larger  digit display , and it sits
  immediately below the  Viewer window , convenient location )

Below the  time code digit window , is the
Device Manager window , sitting in it's own dock ,
as a floating window .

below that , in the Lower Right quadrant , are the
main 4 or 5 windows of Vegas interface .
All docked on top of each other .
Click each Tab , to select one of the interface windows to view it .
Left toward Right Tab listing :
Media Pool  Explorer  Generated Media  Transistions  FX  Trimmer .

On top of those 6 interface windows ,
is the large Surround Panner , docked as a  "Slider" window .
i slide the panner to the Left to "view the Panner"
when not using the Panner , i slide Panner back toward Right
to close Panner , then i can view the 6 Tabs of interface again .
Typically , i never use the 6 interface Tabs , when working with
the Surround Panner ,... so sliding the Panner on top of those
6 interface windows is no problem . ( share the same space )

On top of the Surround Panner Slider window ,

is the  5.1  surround  meters window .

docked as a Slider window on top of Panner window.
( "Preview level meter" is  OFF )
To turn on 5.1 meters to see them , go into
Properties  Audio Tab and select 5.1 instead of  Stereo .

The 5.1 meters are slid to the right to make just more Room , and then is Never moved again . only the Surround panner window is slid left , when needed . Thus the lower right quadrant is one docked monolith set of 8 windows . And this monolith set is , itself a floating window , as it is NOT docked to the Time Line .

Be sure to Save your Custom Layout . ( Vegas Menu :  View-->Layout )
Be sure to Backup the Layout file , to a USB drive .

Every window has a  Text  Tab . Left mouse click
hold and drag the text Tab to undock\move a window .
When re-docking , press and hold  Ctrl  key .

The above has always been my pro Layout . Conceptually ,
the very first time when i was "getting there" , took a few hours .

i always want a large "vertical stack" of tracks .
track width is no issue here .
Large Viewer is  one fourth the physical TV\monitor .
i have easy access to Scopes , large scopes .
i have larger digits  time code that sits with the Viewer .
i get to see 5.1 level meters ( always visible ) .
i have easy access to the Surround Panner .

note about the  Viewer :
i always keep Transport control  OFF .
i always keep Top menu bar of  Viewer screen , OFF
Thus , the  Viewer is "Just the Video" , no wasted physical space .
Space bar to pause\play . Transport buttons are at the bottom
of the  time line anyway .

P.S. This login made a new forum profile , all previous stats are gone !

didn't realize I was at vegascreativesoftware forum . ok .

Magix profile is still there . 2 different forum locations .

Thanks… Note that if you take a screenshot you can upload the image.
