Attachment viewer

It would be nice on an ipad pro to be able to open a file attachment in split screen mode so that I can reference attachments while writing notes. Is there another way to do this?

on any ipad indeed!

Have you seen other apps that do this? Examples?

I think the best you could probably do is to open the attachment in a different app, and put that other app in split mode with Agenda. Of course, you can’t edit, but you can view.
