This is real project screen with complex UI that was switched
from using the MVP with Moxy library 
to the use of RxPM pattern (Reactive Presentation Model) with Outlast library (persistent PM layer).

I was doing it to see pros and cons of the RxPM pattern. 

Pros: 
- easy integration with RxBindings for complex UI.
- nice saved states in PM (for PM and MVVM lovers). 
- easy combining of reactive streams coming from network, db, etc. in PM.
