In the color scheme, it would be highly beneficial if we could configure an alternate color for clicked links, so that users can easily see which links they've already clicked on.

This is especially important from an accessibility standpoint, as users will frequently skim a list of search results or activity to find new content they haven't clicked on.

When a color is set in the Linchpin Theme for "Global Link Color", the links are that color, whereas default Confluence will change clicked links from a darker color to a paler one, so it's easy to see.
