Visitor lists - yes. Obama was the first to release the lists openly (even then some was redacted). So this is closer to the norm that releasing them was.
Taxes - give up, he will never release under any circumstance short of a court order (and that isn't going to happen). He lied, will continue to lie, and he doesn't really care.
War - I hope not but... He'll go nuts if NK makes any offensive move. A attempt at Pence, a missile anywhere near the carrier group, and all bets are off. I half expect South Korea to order the US out of the country to calm things down. They have the most to lose regardless of what happens. The south does not want reunification - it would destroy their economy for years to come.
