I would like to create a mobile app that lets users open files stored in their Keybase (as long as they have the Keybase app installed on their phone), even in the private folder.
As Keybase does not seem to support that yet, I am integrating with DropBox instead. They offer several options to do this, including SDKs, a REST API and a simplified Chooser, which just adds a "Choose from Dropbox" button to the app, which then lets the user select the file to be opened from the Dropbox folders.
It would be awesome if Keybase could support the same thing.
