@hieuwu thanks, could you also tell a bit about motivation behind these changes ⏤ what goal you want to achieve by the refactoring? Maybe pros & cons of MVP and MVVM

Am I right, that some parts of current codebase will be removed when you complete this PR? I see only additions right now

Yeah I am writing a document that includes current code execution, pros/cons & how to analyze current code then convert them to MVVM step by step. One thing I can reveal for now is that it would help us a lot in adoption to Jetpack Compose if we want in the future.

Yes, current code could be removed after we complete testing for new one.
