Not sure how hard this is to do, but it would be really nice, is to have emails submitted as tickets to keep the color that was submitted.
Reason is my clients submit html/outlook rich text which shows red or other colors of things they want changed or updated, just to be clear. However, once inside the ticket, I don't see any color at all. (Luckily, from the server side, I get a CC of all originals at another mailbox so I can see what they really submitted originally, with the crossed-out text, colors, etc.)
In a related feature request, it would be nice to be able to put [code]...[/code] and just have it marked as code in the ticket and in the forums.
