Components

Application keybase is an open source application which is a messanging platform where users can write for every twitter, reddit and facebook. Users do not need to know someone's phone number or email address. All messages are secure, end-to-end encrypted, multi-device: user messages persist and transfer with encryption for new phones & computers. As a user I can not find any other important and interesting features in this app.

Proposal

I propose to the developer to add features:

Security verification, useful for securing private and group apps and conversations so conversations in this app will be more secure. This security verification can be done with passcode known only to the user.

Turn off notifications, users can turn off incoming notifications for some time that the user wants. This is useful for using time to rest or do not want to be disturbed without the need to turn off the phone.

Mockups / Examples

Here is a sample image after the developer added the feature

Benefits

With the security verification feature the user can secure the application and private or group conversations with so the conversations in this application will be more secure. This security verification can be done with passcode known only to the user. That way wherever the user is not to worry about the conversation known by others. Other users can only open the app on the main screen without being able to enter into private or group conversations.

With this feature turn off notifications the user can turn off incoming notifications in some time desired by the user. This is useful for using time to rest or do not want to be disturbed without the need to turn off the phone. Indeed this feature looks trivial because it can turn off the sound on the user's mobile phone. But this feature in addition to turning off other users notifications will get a notification that users who turn off notifications are busy or are resting.
