The compose email box in a webmail client, like the one Gmail displays in the bottom right corner.
Alternatively, you can put user options there too, like a sort of floating toolbar. Sites like Medium do this in their WYSIWYG editor, and some of my own sites do this to display such options to logged in users.
Oh, and media players you might want to keep open as you scroll down the page/through the site. YouTube has a miniplayer option for just this, and a site with a music jukebox might want to use the same thing there too.
And yes, those mini carts you see on ecommerce websites when you add a product to your basket.
Well, your web app vs web site distinction is very arbitrary. For example, imagine if it happened to be "it's a web app if it can benefit from position:fixed". Then your input isn't going to be very useful here.
Also, your accusation isn't warranted. Just because someone doesn't know your arbitrary distinction between web app vs web site doesn't mean they ignored the person above them.
I don't think most people would consider HN suddenly a web app if it upgraded its <textarea> into a wysiwyg markdown box.
> Well, your web app vs web site distinction is very arbitrary.
It's subjective. Your assertion that it's arbitrary is unfounded; you're clearly not even trying to imagine what a reasonable definition of that distinction might be.

I'm pretty sure HN wouldn't need to abuse position:fixed to implement a WYSIWYG comment editor.
