I’ve made an open-source icon-manager called Icon Drop: http://icondrop.io/
Essentially it gives you access to thousands of SVG icons that you can easily drag’n’drop to Photoshop or Sketch. It is faster than googling/downloading icons IMHO.
It already comes bundled with Material Design and Font Awesome icons!
Hope you can tell me if it REALLY helps you be faster at working with icons, that is, HERO or ZERO?
