For those of us who forget to hit the green button

I admit it. I make changes on the options pages, get excited about seeing how they will turn out and FORGET TO HIT THE GREEN BUTTON which Flynn so kindly made big enough so we shouldn't forget to press it. What I'm wondering is: Is there a line we could add to the code so that whenever we leave an options page the page saves our new settings without us having to press the green button. (This would also save a lot of scrolling down to press it when making a lot of changes)
