In Land options, right below "Avatars on other parcels can see and chat with avatars on this parcel" please add a setting for objects as well. This would be for the public channel.
I'm particularly inspired by visiting a parcel with the game "Coin Clash" running, and rapidly being struck by over 100 shouted messages from a neighbor's parcel. The people I was visiting groaned "oh, that again? we have all that stuff blocked, block all the messages."
So, yay, blocking is an option, but imagine having to tell every visitor to block every new game someone comes up with that screams into their parcel?
And writing this reminded me of a concern I'd had with a neighboring parcel in the past: their 'friendly' barkeeper bot that listened to our chat and periodically chimed in, from the parcel next door.
Let's add a setting for privacy, please!
