The tui function itself had a few sub-functions and therefore
basically already was class-like. Making it an actual one with proper
methods improved readability.
The curses wrapper was dropped in favour of __entry/exit__ methods
that implement the same behaviour.
Also renamed single character variable name, so the name reflects the
content.
