is there a chance of getting the emote/emoji/kaomoji buttons to insert at the cursor instead of at the end of the textbox?
pretty much nowhere else works like that and it's kind of awkward adding things to a post as it stands, very fiddly

you just split the textbox into two substrings, one with stuff before the cursor and one with stuff after
and set the textbox contents to be the text from the button concatenated into the middle of those two strins instead of just doing it at the end of the textbox contents
