a really good QOL improvement would be if the name was automatically synced up with your current steam name, regardless of if others currently share the name. it would really tie in the steam connection.
if worried about impersonation perhaps a button could be added to the player list to open their steam profile on the steam overlay ingame?
edit: i've also noticed a small inconsistency, on your profile it says your blockland id is 0 when it should be 1 - maybe a resync is in order
