hmm... not yet

Take your time.
I am not going away anyway *wink wink*.

I still haven't discovered how emoticons work here.

you can react to existing messages. but i need to add an emoji button for inserting into new messages

It's not high priority.
I thought that I hadn't figured out yet how.

It's nice to discover new things in the platform like the "Add to playlist" I wrote about earlier.
