The new comparison table show differences of the generic font names of the currently defined icon set and the icon set which is browsed in cases it differs. This makes it easier to decide, what icon set to use
The Awesome Icon library is a free, high-quality icon library which defines in version 6.1.1 more than 2,000 free icons. It can be included in all kind of packages, and it does not depend on a CSS toolkit. It defines an icon font and SVG icons as well. The https://fontawesome.com website lists in addition to the Free version also a "Pro" and a "Pro Max" including more than 13K icons.
The package supports installation from CDN and a local installation, switchable via the site-wide administration link for the package in /acs-admin/package/fa-icons/.
The package is also already integrated with the <adp:icon> markup to support generic pages using icon sets depending on the "IconSet" definition (switchable per subsite).
