Likes are not that meaningful. Choose an emoji like you mean it.

By default there isn't but if you hold the like button you can any emojis of your choice. I did find it odd not to be one of the default as well though.

amethyst could do that already 👍

i like the nostrudel customisable reaction emoji list but actually i think what would be more awesome is a personal frequency preferred list, so you can pick any emoji from the emoji font, and it tracks them so they are sorted by frequency

kind 7 emojis can include images and multiple emojis also, i keep seeing people with disco kitty reactions to my posts
