Color Suggestion:

In my copy of the plugin, I made the change so it’s not an issue for me at all, however may I suggest the following:

The way the colors are set up, when you go form a light colored theme to a dark one, or the icons are over a dark section (or footer), or on a light colored section depending which color scheme you are using, you are going to encounter some visual issues:

What I did was I changed the light color scheme from #dddddd to #999999. I could probably get away with #888 too, or something close to that. By changing the color to #999999 the icons are now visible almost in all situations, both in lighter (white) background, or dark (black) background. As a result I don’t have to worry about changing the color scheme from the plugin settings page anymore, and when changing themes with completely different background colors.

Just a suggestion…
