I'd already be happy about the option to create and manage more than 4 tabs. They are not enough.

I don't really feel the need for emojis, clicking them together takes more time than writing anyway (unless your messenger of choice automatically converts this, like Discord or this very forum.) But I'm also old enough to remember years of IRC use, so maybe I'm biased.

Also, enabling emojis often means including the standard emojis you have at every messenger. These Ascii Art macros are very specialized, people would still post this.
