matteocontrini hi. Yes I know that the picker itself is a feature we don't find anywhere else at the moment.
Flarum has switched from inserting emoji shortcodes (
:emoji:) to inserting the emoji themselves in the text. As far as I know the EmojiOneArea library was designed to insert shortcodes. Also there were already some differences in the available emojis in Flarum and the picker and it will only increase over time because both are based on different emoji lists.
It's certainly not impossible to update this extension, but I'd rather spend the time creating a proper emoji picker extension from scratch with better integration and more options than update this extension. Not sure when I'll be able to do that though.
EDIT: also, more recently I discovered an issue in beta 8 flarum/core#1692 that I'm sure would affect this extension, preventing an easy update 😢
