I've spent the past hour trying to figure out why some emails are yellow/gold colored font. They appeared to be bulk emails so I thought the mail app was marking them as spam, but I wasted 30 minutes trying to figure out where the "Not Spam" button went before realizing the button is missing because these emails are in fact not spam. So why are they yellow? Oh... if there's any Mac developers reading this... ALLOW US TO CHANGE THE DELAY TIME BEFORE MARKING EMAILS AS READ! Sometimes I wonder how the simplest things are left out.
