Request: make text files in iOS Files editable

I can view Files in the Keybase iOS app, but ones like markdown files are not editable. I would like to either be able to edit in kb on iOS, or, be able to "round trip edit" with an app like Editorial.

My use case is, I keep a lot of markdown docs in a Dropbox folder on my Mac, Windows, Linux systems and on iPhone. I edit in vim or Vnote in the OS's and in Editorial on iOS. I would like to be able to stop using Dropbox, if I can only search and edit files on kb iOS app "Files" section.

Start by examining the Keybase iOS app's Files section and how it handles markdown and other text files. Compare the requested in-app editing and Editorial round-trip options, then clarify which behavior is in scope and how successful editing and saving should be verified.
