For the most part, I intend the client to be exactly the same the existing client. But, there are some extra things I'd like to add. None of these will affect gameplay as such.
Extended Sounds props. These will be able to load ALL game music, and also load from arbitrary locations on the internet, including net radio.
Picture props. Load images from the net and place them in your grove.
Text props. Make you own signs from any text.
