I honestly would like to see whatsup continued and improved. I find the interface pretty intuitive (not that it cant be done better, just cant imagine how), and it kind of works (except for profile picture, but well..)

Ideally, i would definitely contribute (and possibly want to join forces) for a Qt(5) based platform for multi messaging, not only whatsapp.
I miss, for instance, a telegram client for my phone, as well as viber, snapchat, etc etc.

It would be truly fantastic to have them all together in one Qt based application, possibly energy efficient, that could also be ported to other OSes easily (at least BB10, Android, Jolla and tizen. don't know about the exact limitations of Qt on iOS).

Am i delirious?
