There should be a little notification, maybe in the top left chat log, when a player joins your crew. Sometimes in public it's hard to tell if someone new has joined yet, and you just kind of have to check "My Crew" repeatedly.
While this isn't a big deal, I feel like it's one of those small quality of life improvements that would be nice. I didn't come up with this idea but saw it on reddit, so credit to /u/tbrady1001
