Some request

[hhhhczh]

I need to keep the screen constantly lit only when displaying lyrics, but not need it in elsewhere.Please add a swith about it in the lyrics settings.

And,the number of levels for setting the font size of lyrics is not enough. The smallest font size displayed on my device is still very large. I hope to add a smaller font size option or change it to infinitely adjustable.

Add a switch that needs to be pressed the back botton twice in a row to exit the app. I often accidentally touch it in once and the app exited.

Consider adding AB repeat function?

Thanks.
