All available themes have the same color for visited and unvisited links #15
Description
This is the default theme, and I've visited SCP-5000 and SCP-5002, which have very slightly darker link colors.
Sigma9, with no link color change
Night mode, with no link color change
Minimalist white, with no link color change
Matrix, with no link color change
Navy, with no link color change
Sandstone, with no link color change
Amber, with no link color change
Darkbody, with no link color change
Shark Punching Center, with no link color change
This is a bit of a problem, because I can't remember offhand which of several thousand SCPs I've already read, and it'd be nice if at least one of these themes marked visited links.
