[Plugin: Subscribe / Connect / Follow Widget] Code so buttons open in separate tab or window

Nice Plugin!! However I would like it to work that when someone clicks on one of the buttons that the destination page opens either in a separate window or tab.

I use target="_blank" in my posts to get links or photos to open in a separate window or tab but I am not sure where I would need to add the code to make this widget work that way.

Any ideas?
