Thanks for reply. Good to know I'm not alone here paying attention to such nuances.
Yeah, I've noticed that Full Lyrics are somehow more comprehensible. But, again - as the folowing line jumps into 'current' position and, at the same time, font is increased, you just comprehend this as a different text and have to read it again. Far from a perfect solution to help you follow along, isn't it?
Yes, it's really awful. As your eyes start to focus on the next line, it's font jumps up, and the line jerks up. Extremely hard to follow. And center aligned text also bad for reading. Your eyes are forced to scan to a different spot to start reading on each line.
I'm not sure how it could be designed worse, honestly.
Back when there were Spotify plugins, there was a lyrics plugin that worked really well. I wish I remember how they did it. But for starters, if they could just do smooth scrolling it would be tolerable. If not, then scroll by page, not line.
