Allow to add custom icons in all icon displaying features


would be great to Allow to add custom icons into the icon library or directly in each icon displaying features such as in animated columns for example where you can only add the font icons from list and not add your own topic related icons in png form or any other form. also in the icon features allow to animate the icons with the css animation in every type of icon display. also would be great to to have combined css animation such as spin and flip etc.
