FEATURE : Possibility for "spectators" to see squares highlighted by the players during the game

I'd like to suggest the possibility for players spectating a game to see (in real time) highlights that players add during a game.

Of course, some players might prefer to keep their highlights anonymous so there would have to be an "on/off" button in the preferences. Same story for spectators unwilling to be distracted by any highlights.

It would also be appropriate to differentiate the format between white's highlight and black's highlight (shouldn't be too hard, different colors or different border styles)

This feature would prove to be very insightful during a game like Andrew Tang facing Magnus Carlsen for example :D

Have a great week,
