Space between icons

Try going into the settings page, finding the “size” option, changing it (and changing it back) and then saving. Does that add space? There’s a bug in the current version where that doesn’t get set sometimes.

Otherwise, you can add this to the custom css settings field, adjusting the number as desired:

.fsml_fflink img, #fsml_twfollow, img#fsml_ytsub {
margin-bottom: 5px;
}
