IOS: how to set a default text editor for the Files app?
In the Files app (IOS 11), when I tap on a plain text document, it opens in 1Writer (a pretty good plain text editor I have installed on my iPad). Although I‘m fine with that choice, I was wondering if and where the default text editing app could be changed (I know that I can use the share button but this requires extra taps and swipes). I can find nothing in the IOS settings and only an empty internet on this. Any ideas?
