Feature request: emoji button

[MarcAnt01]

Description of feature or change
It'll be handy to have a separated emoji button next to the one to attach files. So the one to attach files would directly attach files. These way in both scenarios one click will be required instead of two

Rationale
Discord has a separated emoji button and so do most of the messaging apps (Telegram, Whatsapp, Skype etc.) the reason is simple: emojis are often used in communication and users would like to have a quick access to insert them with few additional clicks required
