I have just opened the app on both my computer and phone, so I'm sorry if this has been discussed already; I wanted to jot down a couple of ideas:
1. It would be nice to have cloud compatibility for different clouds than drop box. I use normally One Drive and Google drive, I had stopped paying for my dropbox account, but I had to resume my subscription to use this app
2. There needs to be a formatting option in the mobile app. The text only shows as plain text; you cannot centre it or use any bold or italics. To do this, you need to open it on the computer (and the format is *not* kept on the android version, which makes the big block of text very hard to read on a small screen). Also, the spacing of the paragraphs gets lost: I have mine set up as 200 between paragraphs and 1.2 line spacing, book antiqua font, but when I open the android app, all that is lost (this makes the big block of text very hard to read on a small screen).
3. It would be nice to allow a comment feature on both versions so that writers can share the folder with an editor or a beta, and the person can add comments to the work, which the writer can work on. Since you allow cloud sharing, this could be possible if the beta or editor also uses yWriter.
I'll keep exploring the app, but these are my immediate feedback ideas. I hope it's helpful! The app looks good :)
