i dont know if this feature is already there or not but i just want to suggest if its not . how about adding when typing the emote in twitch chat message bar it shows the emote and then you can click it like when typing twitch global emote. that would make it a lil easier . also emote link or copy from others by only clicking on the emote they sent the text will be copied to the message bar automatically . (and sorry for my bad english).

the first part you suggested already exists.
the 2nd part is a good suggestion, you can request stuff to be added to the extension in #1085995849965899806
