Dual-line desktop floating lyrics support

[AidenYang1]

Request to add dual-line display for desktop floating lyrics, so that the next line of lyrics can be accurately tracked.This is super useful in karaoke mode. Thx!

this is much needed

I propose triple line, one for upcoming line and the other for completed line.

+1 for this feature! Being able to see the next line in karaoke mode would make it so much easier to sing along. Hope this gets prioritized!
