First, I really like this plugin, simple, flat and can easily be modified to fit site design colors.
Just wondering if you plan to offer the options for Titles or ALT tags or ABBR tags in the future? I realize that most icons are pretty branded, but some could use a pop-over title to assist the user, especially if they are sized small.
I tried coding the link with a title tag like http://www.facebooklink.com with no luck. I will go poke around the code and see if I can figure where to add it easily. Care to point me in the right direction?
