Please add additional default zoom percentages for 15" and 17" laptop screens. BACKGROUND: As a college student, I read a lot of academic articles and PDF textbooks. However, I get a little irritated every time that I have to manually type in a zoom percentage of 250% or 270% because the default percentages jump from 200% to 300% (which is TOO much)! I know. It's a menial request. But it would make a HUGE difference for someone in my situation. Thank you!
