Refactor code to separate concerns
This is not a bug, but just a list of possible code improvements that I had written down on paper earlier.
- Centralize rule parsing.
- Separate properly or merge completely UI and non-UI models.
- Move
pickCell()and/orallNodes()functions to proper container. - Investigate the dangling cellValue object (might have been addressed already).
- Rename some functions/classes for clarity and consistency.
