A while ago, a purple indicator was added to the left of each unread message, which seemed superfluous because unread messages were already highlighted in white. It looks like other users requested this feature, but I don't want it. Just recently, I noticed that the titles of read messages have been grayed out, which makes them hard to read in some themes. This adds a third way to distinguish between read and unread emails - but there only needs to be one, and it shouldn't interfere with my ability to read. If other users prefer these changes, that's fine, but I'd like a way to customize these settings to suit my preferences. Could you please add additional customization options to the Appearance section that include the following settings?

• Whether to highlight unread emails in white
• Whether to show a purple indicator light next to each unread email
• Whether to gray out the titles of read emails
