I'm still trying to get my head around the new ways Mail.app is handling Gmail. The latest oddity is that some of the Rules I have set up to make the universal inbox a little easier to manage. I have rules set up for each of my different accounts to change the background of the email to specific colors. I've had a bastard of a time getting this working right since upgrading to the GM. Even when I control-click a single email and Apply Rules, nothing happens. Mainly an issue with one specific account, which would naturally be my main account. thoughts?
