I made this for someone to use at their request. You may not care or need to use this if you are not that person.

**What this Custom Requested Userstyle Does:**

+ Is intended for the Light/Gray Theme
+ Changes that background color of all messages in the message list white (with 90% opacity)
+ Adds a red marker to the left of each email in the message list that are unread
+ Changes the text in some places to pure black from the dark gray
