Master Key still lacking
|Target version:||v15 - AWESOME APP|
The master key can only be set once, at first use, and I found no setting to change it later (had to remove all App data, from the app manager).
Also, at the Master Key prompt, back button doesn't close the app, which forces the user to go back to the main screen, or type the password before closing the app.
The app is great, but tiny details like these would extremely improve usability.
