It would be a great tool (especially with pixels being an item now) to have a room item counter that could tell you how many items are in a room. That way you can plan rooms accordingly if you're building rooms that are item heavy.
A server status indicator would be ideal in letting us know whether it's online, offline, or under maintenance.
Be it a feature on the site or just a thread, I feel this is a good to have feature, especially when a game is in beta.
