I'm not sure if anyone else has taken any notice of this but when you switch to Classic view in the Mail app, the message contents appears on the bottom. I would much prefer to have it on the right. I wasn't able to track down any setting to change this. Any idea on how to change this behavior? Oh, and if you are not using Classic view, it's great when you have a lot of email as it gives you more space on the screen for messages and you can see more.
