STEPS TO INSTALL extract the zip file copy the folder paste it in \Program Files\Inkscape\share\icons open Inkscape go to edit > preferences > interface > theming change the default icon theme to 'premium minimal icons' DISCLAIMER this is an opensource project to make a better icon design system for Inkscape. i do not own all the work, rather i assembled many of the icons from awesome contributors like - logos by nick and 7kv929, as well as i designed some of them. yet there's a lot to do to make it complete. you can also contribute by making minimal icons (as many quantities as you want). You can DM me if you are interested contributing and feel free to give any kind of feedback... (consider sharing this project to spread throughout the Inkscape community.)
