A picture...

“A picture is worth a thousand words.” -Napoleon Bonaparte.

“Unless you're being paid by the word.” -Me. 

What the world really needs is a PrintScreen-key utility that saves the captured screens to full-sized gifs in a specified folder. Ideally it would be integrated with a keystroke-macro thing so you could capture several screenshots at different stages of a task, all in a single run. Market it to magazine columnists and book authors, you'll make a mint (if they ever get paid).
