What coldtea mentioned, the examples in the site you linked look better (well, most of them, some still use these pointless gigantic buttons). And the thing is every time i see the Textual linked here, it isn't with screens/examples like in the site you linked but with screens/examples like in the official site linked above.
From what i see the screenshots in the site you linked at are from programs made by others instead of Textualize themselves, so perhaps they should take a note of how the people who actually use their library and make TUI applications style their programs and redesign theirs accordingly.
