Thanks for your kind words!

Support topics should be posted in the plugin’s support forum next time, but I’ll save you the post.

Just add some “Additional CSS” code to your site, for example, where #fe0000 can be any color:

.addtoany_list a:hover .a2a_svg {
  background-color: #fe0000 !important;
  opacity: 1 !important;
}
