Simplify the code

[turbolay]

📖 TL;DR - Too Long, Didn't Read

Make the code simpler by refactoring.

🌟 Specification, Scope, and Features

Many controls or backend components are just a melting pot of features that are too hard to understand, I can't have a direct list because one really has to have context on a component to understand that. The CoinsRegistry is a great example that would need some love. Same as the TransactionSummary that is basically adding complexity for the sake of adding complexity.

⚔️ Motivation

Too many pieces of the software are being increasingly complex over time for the only reason that we are adding layers and layers each time we find a problem. We could refactor many classes to make them much more easier and don't rely on many different objects. In some cases renaming variables could also help.

• This is something that we do anyway. @lontivero
• Too general. I need concrete ideas on what, why, and how to refactor and what is the benefit. @molnard
