Since Christmas is coming, this is my wish.

I work in Acrobat DC Pro daily for multiple projects. Each project has multiple PDF files.

I use tabs within a Window. So my "Open Documents as new tabs in the same Window" is selected.

What I wish for is to be able to have TWO Adobe windows open, each with their own tabbed PDF files. Thus, I would be able to have one project window open and have tab access for all PDFs for that project. The second Acrobat window would have a second set of PDFs, all listed in the tab ribbon.

Another variation of this would be to have nested tabs. This would allow me to drag PDF tabs onto one tab and the PDFs would then be in a dropdown list associated with the tab.

Crazy? Maybe. But I think this feature would greatly help workflow when working with many PDFs in different projects.

BTW: This is what I do with Safari. Two windows, multiple tabs. You can see this feature at work in Safari if you open a New Window.

PS:My life would be very different if I didn't have your excellent software suite. Great Job!
