Yes, I know which things are buttons, which things are text entry, and which are checkboxes. This was a strength of early 2000's UI design, and it's a shame that so many applications don't give such clear indicators any more.

This application still has an absolutely crap design.

* How do I specify where the downloaded data goes? Why are there onscreen options for literally everything else, but not that?

* Which text entry fields are disabled, and which ones are enabled? This is something Win95 got right.

* What even is "force directories"? And it looks like checkboxes are used for both it and "no directories", so what happens if I check both?

* What's the difference between Spider and Recursive? Those sound like the same thing to me, and I know I'm in a pretty elite club just knowing what web spiders are at all.

* Are jpeg/gif/etc only used when Reject is turned on, or are they also used when Accept is turned on?

* Is the wget-list input field connected to the Input file checkbox? It's right underneath it, and presumably I have to specify the input file somewhere, but the spacing implies it's not.

* What's the difference between "quiet" and "non verbose"? What happens if both are turned on?

* The rest of the buttons are pretty well labeled, but what's AG?

* Does it really need its own quit button? The window manager already provides one.
