Future Tech Roadmap

In no particular order

Add in-memory and locale cache for rate particular to currencies to reduce Api request calls conversion
Setup Ktlint on the project
Migrate to KSP and K2 compiler.
Use the Konsist library to write rules about the architecture and class conventions.
Set up macro benchmark and fix memory leaks.
Replace BuildSrc, migrate to using version catalogs and update App Dependencies.
Add screenshot and UI/integration testing,

Product Roadmap

Add widget
Add live rates (5) and a view more screen.
Add favourite currencies to have on the live rate list and potentially have notifications sent based on a price drop.
Add a local profile screen with the possibility of having a remote profile in the future.
