https://ratatui.rs/examples/apps/demo/ is pretty much the oldest untouched remnant of code from tui-rs days (pre-ratatui fork in Feb 2023).

Ratatui itself has a lot of much nicer AI generated code in it since then ;)

We've also done a bunch of things to help drive down some of the boilerplate (not all of it mind you - as it's a library, not a framework like other TUI libs)
