Refactor to hook-based solution

[elmarti]

Is your feature request related to a problem? Please describe.
This project was built as an experiment and as a result, although it's using fairly valid TS, most of the code lives in a single file.

Describe the solution you'd like
Refactor the project to be more granular and use a functional component/hooks.

Additional context
There are a few open feature requests, which I think would be better solved with a functional-based solution

Now working on the branch #hooks - mostly working, a few things to debug
