I will say that I do quite like the score estimation as it is, drawing the squares on the board as a toggle on and off, specifically after a game is finished.
It was one thing I though was quite cool that AI sensei had in their reviews, that one could visualise the territory on the board.
I also prefer the way OGS puts the score/% loss on the moves rather than AI senseis A,B,C… etc but now OGS also has a way to display the counting on the board, which I think is a nice touch for reviewing.
