No, details are not worthless. The issue is that you are applying absolutely no importance to crucial details. Specifically, that to implement your request (as you have stated it) would break Solo mode, as it would no longer be Solo. It's really simple.
That's all lawyers actually do. Not really sure that there is a point here.
Agreed. If an extra pip is not an issue in Open mode, why would it be an issue in Solo (in fact it should be less of an issue, as no other player is affected...). Really, it isn't the functionality that is the issue here, it is the request of turning Solo mode (single player) into Multiplayer mode. If people are unable to see that this is what is being requested, then there really is no point in continuing the discussion. Which is the action I'll be taking now.
