This app is clearly a demonstration of GTK4's light/dark transition animation. Looks like it works perfectly to me!

Same for me.

What info does it show more than a:

"netstat -tulpn"

Wrote myself a script years ago that basically loops netstat -tulpn watch like for the same purpose - just wondering if your tool shows me more than that.

modern graphical interface, for a start

I was asking which information it shows not what output it uses to display that information....

Come on, now. You can see that it supports today’s most critical feature: it has dark mode and light mode.

/s

If you live in the terminal it's all dark mode*

* unless you are one of those weirdo's who has a black on white terminal in which case you should be on a watch list (/s in case wasn't immediately obvious).

I've been there since the DOS days when it was all dark mode, green phosphor characters on a black CRT. I was there when amber monitors were the new thing. (I still love sunglasses with brown lenses.) And I watched the early Apple computers with graphics and black-characters-on-white display style that has been the rage ever since... well since the recent new thing being dark mode.

It reminds me of fashion trends, miniskirts then maxis, up and down past the knee like tides.

Fads, that's the word.

I am exactly that kind of weirdo, but then again I’ve been reading black on white books for my entire life and I never thought to complain about it.
