In the Now Playing tab you can only change font/size of lyrics on the right sidebar. I would like to be able to change the font/size of the lyrics in the right/left Main panel as well.
Currently, The custom highlight color is the only lyrics setting that gets applied. The only way to change the font settings for lyrics in these panels is with the default font settings (which is not desirable) and it only affects the font size, not the font choice.
Actually, while writing this, I realized that the other tabs/views already have this functionality. The settings for lyrics just get moved to what ever panel they appear under. That would be great if it worked for now playing as well.
