@andstatus Yes, I understand it and I like it.
For me it's better to not to make grow apps for optional features, and in this way every developer can improve his code.

But for inexperienced users will be a little difficult. Yesterday I was checking !xmpp features with #Conversations, just the use of QR codes with a friend. When she tries it out Conversations ask for Barcode Scanner app, while Whatsapp have been integrated the code at his app and don't need external ones.

But yes, again, I think we must to teach newbies the better way. :)
