The parent refers their examples in the TFA:

https://textual.textualize.io/

Their examples in the link you sent are OK, the doc examples look crappy, and that's whats in the linked post.

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.
