Some things were pulled out of adapters to fragments. New classes were introduced - StatusViewData and NotificationViewData. They not only have view state in them but also help decoupling.
Because introducing parallel model list requires a lot of synchronisation PairedList was added.
Also synchronisation between fragments and adapters is quiet tedious and error-prone and should be replaces with better solution.
Oh, I also couldn’t resist and fixed bug with buttons animation in the same commit.
