>In other words, the font you set up for your message will be the same font when it show the thread in Simple Format, correct? (I thought there was a separate setting for the font for Simple Format Thread Display).
There was no class bound to it in the simple format. I adjusted it in the last hour. For the font size, when viewing a single message and other related messages, they all share the same font class. I don't think there is a need to have special classes for various locations.
