I've read that Macintosh computers have a green resize button which, when clicked, resizes the window only to the point of removing scroll bars, as much as the screen resolution will allow.

I use the programs Epiphany 2.20.1, pidgin, nautilus, Rhythmbox and Evolution primarily. Not sure why I bothered looking up the version number for Epiphany ...

Is there a way I can add that button to my windows, to resize them that way? If Mac has written software for it, then surely we have as well? (I found Desktop Drapes to rotate wallpapers, as the new iMac computers do...)
