Great theme customization tool for Reddit. The only thing that bothers me: the only theme which allows to use custom colors to change the color of posts topic is "legacy" one. If you choose any other theme - posts topics will be white (unread) and grey (read ones) in color. But it would be really nice if you can set any color to unread topics, to distinguish them from read ones more easily.
And maybe a color picker, instead of predefined colors, would be nicer, but this is not a dig deal.
