I just like good old MDI I guess. 
Sorry to be such a pita.

You can still use MDI.  Just undock the docked views, (right click a tab, pick undock, or drag out the tab) then click on the system menu (top left corner of the caption bar) and make em MDI (click on disable floating)  Save the project or save as a template and it will keep the MDI setting for the open views.

I like the multidoc and the keyboard shortcut D. But is there a keyboard shortcut to tab between screens within the multidoc?

Don't think so, at least if there is, I've never found it

It can be done using...
 
Ctrl + Shift + Tab and navigating with the left/right arrows.
 
Had to experiment to remember it but I knew it was there somewhere.
 
Bit of an awkward keybinding but I'm sure it can be changed in Prefs.
 
Cheers!

Thanks.  
But it is only  Ctrl + Shift and navigating with the left/right arrows.
If you include the Tab it flips the Windows 10 screen :-)

You can attach a shortcut to this function!
