Looking to import Google’s Material Icons (580 of them) into Oxygen with just a couple of clicks as a custom SVG set?
Download this (mirror) symbol-defs.svg file, go to Oxygen > Settings > SVG Sets, give it a name and press Submit.
To use the icons, in the Oxygen editor add an Icon component, select “Google Fonts” from the Icon Set dropdown and delete the default “thumbs-up” text to see all the icons. You can of course search to filter and click on any icon to add it to your Page/Template.
