Set and New Interface?

This set is deceivingly easy. These people are smart and creative asf in inventing new variants. omg. Why the new interface with the "game set up", "real time", and "question explanation" buttons? Why not do something actually improves quality of life, ex, be able to click on the webpage while playing the explanation videos(or drag the video window around), so that I can check the questions without automatically close off the video all the time?
