Hey, thanks for the kind words! 
If you’ve got a cloud storage (which I recommend having for extra backups of your work anyways!), you can definitely write on the go with another app, save your work in your cloud storage, and then bring it all together in Papyrus when you’re back home. 
glucose has a good example here on how to set up your cloud so you can sync .docx Word files over to and from Papyrus: Any plans to launch in ipad ios? - #13 by glucose
You can export Word files from Papyrus by going “File” → “Export” → “Word .docx…”, and you can bring in .docx (or .txt, .rtf, almost any file you’ve got!) in by just dragging the file into Papyrus.
If you’ve got an exotic cloud storage or device set up, let me know. I’m sure we can find a good workflow! 
I don’t have a scoop on the app. It’s something I’d love to see too, but for now no news. I expanded a bit on this here: Papyrus Author compatible version for iPad OS
Awesome to hear from you, have fun with Papyrus and let me know how it goes!
