Pages Documents

Yes. I currently have 30+ documents open in Pages.

"Open" does not mean "simultaneously visible" though.

That's possible in Pages 5 and later by sizing the document windows for two docs to half the width of the screen, and placing the two side by side.

The current version does, I think, allow placing different open docs on different tabs, making it easier to switch between them that picking a name off a list in the Window menu, but I don't know if it permits side by side viewing more easily than can be done in earlier versions.

Regards,

You can also have the same document concurrently open provided that it resides in two different folder locations.
