As someone who primarily plays on mobile, and doesn't have very good coordination to begin with... (Also dirt slow internet speed) I'd love this to be a thing. While adding people as friends randomly isn't an incredibly common occurrence... coming from Flightrising (Which sadly also doesn't have a confirmation for this...) I found out some people hate it so badly, getting randomly added, that they will block you. I'd love to not have to send a panic apology note to someone because of a misclick. If this could be added, I'd be really happy.
