Side by Side PDF files
I often have two PDFs open at the same time, side by side, for referencing purposes. Now with the Acrobat DC I don't have that choice as both opened files are now in the same 'tabbed' PDF window. I can see the two files 'serially' but not side by side.
What to do?????
You can drag the newly opened tab out and your PDF will now be open in new Acrobat window.
