adding barcode to add friends and deleting account on keybase.

Benefits

Adding friend using barcode will be of great benefit to the users. it will allow them to add friends instantly without waiting so long for approval,the moment both parties agree to scan barcode on keybase app, they become friends instantly and also with this feature, strangers cannot add you up as a friend, only those you wish to chat with can have access to be your friend through barcode scanning since there has to be a face to face interaction before such measure can be achieved.
The delete account that comes along with reason for deletion feature will serve as a means of ripping off unwanted account. sometimes, user might want to change his account due to private /personal reasons, deleting the previous account will be more okay than forfeiting it and this in turn will make the developers know how many people are really using the app presently,how many deleted account and reason for deleting it.this on another hand will serve as a means of communicating with the developers on users view about the app because i believe some will have to delete due to certain unsatisfactory encounter while using the application. All these will brace the developers activities to improve the quality of the app.
