Hand signs to interact more

Dear developers,
It would be great if EMO would recognise it when I wave my hand :wave:. Maybe he can react on it with a simple Hi! Or Hello #NAME… It is just a simple thing but it would really increase the interaction without the need to call EMO’s name first. Maybe there are some other hand signs possible like a thumbs up for example, EMO reacts with a ‘Thank you’. Or a Peace sign :v:, EMO will ‘Peace’ back. :wink:
