Softer scrolling for notes in wait mode?

[HansHermann123]

Hi, I notice that when I use sightreading trainer in wait mode for a while, the rather abrupt movements of the notes get stressful for the eyes. Would it be possible to use a softer scrolling? Maybe something like ease-in-out in CSS or so? Not sure which is the best option here for prolonged use, I'd volunteer for testing if necessary :-) Thanks again for your fantastic work!
