Yea more for house transfers and such, where 100's of mill on are in a trade window.
But the reason I was looking was I was brokering a castle sale, and I was in possession on hundreds upon hundreds of mills, and I didn't want to have to hover over each damn check to see if it was 1,000,000.
Which I ended up having to do. Was only shorted 840k. Not bad! Although, someone should make a script to count the checks, and their value in all open bags. It'd be an awesome late (or early, depending how you look at it) birthday gift.
