Improve synchronization of lyrics on Bluetooth devices

[Chomuske]

I would like you to add an option for Better sync lyrics with Bluetooth devices, like advancing or delaying the milliseconds between the lyrics and the voice or something similar, Thank you.

Thanks for the request. Actually, we already have this kind of synchronization for Visualizations. Probably this latency can be also applied to the sync. lyrics UI. Though, BT latencies are rarely more than few hundreds ms, and lyrics UI already have resolution of 250ms, but anyway this will help a bit.

(The visualization delay already can be configured per device, so this definitely can be useful for lyrics display as well).

Podia melhorar um pouco a forma de alteração desse delay, porque aquele slider nas configurações de dispositivos é muito difícil de colocar numa latência especifica. Botões de aumentar ou diminuir, ajuste fino, poderiam ajudar nisso.

The visualization latency is now applied to lyrics  - build-984.

@maxmp Thank you very much for adding this option. I realized that the option had been added a day after writing by this means, but I forgot to come and comment.
