I give it only three stars because it doesn't allow to do something as simple -yet so useful, as to specify the desired color in settings. Just a simple box where users could set the hex color. Sometimes the default shade of red is too annoying or has too much contrast.

Works as advertised. Would be nice to be able to set the color or have it more adaptive, since the red color is not as easily distinguishable if the link's color is already set to some shade of red.

Nice, simple, efficicent. Thanks!
