@jfml @latenightlinux ALRIGHT i've been digging around in the settings for heliboard, and there is currently implemented support for something approaching emoji search by prefacing your text with a : colon, not unlike what i use when shitposting on mastodon. it's a toggle switch in the heliboard settings called "Inline emoji search". you enable that and it will show a popup to go download an emoji dictionary from a repo on codeberg, after which you install the dictionary on the keyboard itself by navigating to Dictionaries -> "Add dictionary from file" inside the heliboard settings app
tl;dr - looks like they have emoji search
