!! Better use Icon Shortcode Plugin !!

[Kettenotter]

This plugin isn't updated anymore. But still further at the top than https://github.com/aidenlx/obsidian-icon-shortcodes in the plugin list.
The other one supports:

• mobile devices!
• custom icons
• icon visible in edit mode
• emojis

Just leaving this here so people don't need to replace all their icons like me. Also it has the same icon packs which you can download under the plugin settings.

Unfortunately, that plugin has not been updated for just about 2-years and has issues that do not look like they'll be addressed by the author.
