I wanna love this app but right now it is unusable for me. I want to be able to turn off wifi and write, but offline files created in the Dropbox or GDrive folders disappear as soon as you reconnect to the internet, & offline changes you do to files in those same folders also disappear as soon as you go online. I emailed them about this and they told me it should be fixed by the next update, but it's March and it's still not fixed. Also you can't duplicate files within the app for some reason.
