If this action was allways visible independently of having fog or not, it would be easier to navigate the history log in the Native Player, since it has the Next Turn button.
This is specially useful in factory heavy boards, with lots of action between turns.
Don't see much of a downside to it, just that it would in some cases be easier to extract information about a player's turn, but I don't see it as a bad thing.
Remembered we would get to know which players were eliminated from the game. Can't say if that's good or bad, I think some players would like that change while others wouldn't.
