I still agree with this, even though you (and I) forgot about the request to have this as an option.
The player who passes doesn’t have to end the game, right? And the other player is maybe stalling. So it should be on for them. IMO the only good reason to have it turned off is “I don’t want it to show up, because I’m not clicking it anyway”. But that doesn’t seem like an important feature to me.
(I would be in favor of only being able to force the end of the game, once all dame are filled. Which would be the consequence of the suggested chinese-half-point change, if I’m understanding it right.)
