you can save a dopus window - it's called a Lister Layout.
I use this a lot - different tabs / layouts / views for different jobs, for different requirements. (I also use Session Manager to do the same kind of thing in Firefox.)
You can make a shortcut to save a lister layout thus:
Prefs LAYOUTSAVE=single
on saving you get offered some options:

If you change your layout and want to save the changes, you need to save it again, which can only be done like file/save-as, i.e. use the shortcut above, type in or select the name of the current layout => message: "do you want to replace..." => click "Yes". A bit messy, but you get used to it (well, I did :p )
Lister layouts can be opened via the tray icon, or via
menu: Settings >Lister LayoutsBut I use
FARR to open them

....
You need to create a shortcut to the layout:
menu Settings >Lister Layouts >Edit Layouts- drag relevant layout to desktop to create a shortcut
- shortcut has funny name Layout "XXXX".dcf (where XXXX was the saved layout name) - I change name to the saved name
- move to a location that FARR can read (I add them to the Start Menu >Programs folder)
With the
TEST layout example:
