We screenshot something when we there is no option given to save it in the gallery. All of us love this feature, which has made a lot of things convenient for us.
Why not apply the same thing in life? When there is no option given for something which we so ardently desire, create a way to achieve it. Why chose among the already given alternatives? Why not create a new one on your own.
Think about this. It will make a lot many difficulties easier for you, if you discover your own feature of screenshot for any problem you face!
