Hello Calibre community!
I'm excited to share my first contribution! I compiled a new icon theme based on Font Awesome. It is meant to be paired with the new dark theme of Calibre. All the icons are under CC license, and I modified/created a few to fit Calibre.
Please test it out, and let me know what you think!
Here is the source repository with the SVG icons:
