Hiding in plain sight, well not really.
But in the Registry, change Computer\HKEY_CURRENT_USER\Software\Xara\XtremePro x64\16\Options\DocInfo\ShowWebDialogDocInfo to Value 1.

Do this with your application closed. I have only experimented with XDPXv16.2.
On opening you should have File > Document Information as a web page.
Compare with File Document > Info to see the advantages.

As this is tweaking your Windows Registry, do so at your own risk. It is advised to back the Registry before any changes.

Report back success with other applications or versions.

The joy for me is the History Tab.
It shows all the saved file versions with the exact product versions in XDPXv16 as well as Xara Cloud.
