that might become an issue because I modified that file to show the list of previously used emojis… I’ll have to investigate how they replaced it. I’m still traveling so it will take at least another month until I get time to work on my patches.

If you don’t find it, you can tap the little magnifying glass icon in the bottom right corner of the emoji keyboard and use the search feature to find it (just type “hug”). Make sure you’re on the first page of the emoji keyboard, otherwise you won’t see the alphabet keys for searching.
