The new Vertical Split line in the Player tab menu is an elegant simple solution. Thanks!
With multiple Player tabs, it seems one is always the "master". Other Player tabs are apparently subordinate windows displaying the text line "The display for this zone is owned by a different window". Only the master has a RMB context menu in the contents window, which among other things, allows selection of lyrics display for the master window.
The Player "button" (album cover icon, located to the right of the right-side spectrum display in the top header area) is a handy way to jump to a Player window. However I find that with more than one Player tab available, its jump destination can be inconsistent - sometimes it jumps only to a subordinate Player tab, other times only to the master Player tab. So after jumping I sometimes have to switch Player tabs to see lyrics, an extra step.
Please clarify what is going on here with jumps from the header Player button to the Player tab. Thanks.
