Moving text when selecting a word

When in a lesson, wouldn’t it be better if the whole body of text did not move up or down every time I click on a word. I keep losing my place!

It depends on how many blue or yellow words you have. I find it helpful for the text to scroll as I save words or review my yellow words. You can also scroll with the up down arrows, and you can use the minimized view. You can also experiment using a combination of arrow keys and your mouse. In any case I think it is a matter of getting used to it.
