Sakurajima Mastodon Tip: If you are using the web interface, you can leave reactions like on MisskeyFirefish, Akkoma, Fedibird, and Mastodon Glitch-SOC, which has this patched installed at the moment. This feature is still being worked on and will eventually make it to Glitch-Soc.
By clicking the + button, you can leave a reaction with an emoji that is available. In addition, you can click on any existing emoji to leave an existing one as well.
Feditext iOS client is the only client as of now that allows reactions from a Glitch Mastodon instance that has the feature.
