1) Horizontal Pole/Spike Bricks: Vertical Poles are amazing, but they really need some horizontal action here. Same goes for spike bricks.
2) Exit Camera Event: Along with letting the user hit "L" to exit the camera, I say we should have an event for involuntary camera canceling.
3) Client Sided Music Start/End Event: This would be useful for professional RPG's. Music could be triggered Client sided to signal some event or to go along with a certain objective, while not interrupting other players who may be doing something else. People say this cant be made, but I know it can be.
4) Better Tree Bricks: This is long overdue, we need better tree bricks other than the generic pine tree that's about the size of our player. You can build them, but they rack up brick count like nobody's business.
5) Message Box Options Event: Like Message Box OK and prompt events, with just one option that is always 'OK' or just 'Yes' and 'No', I'm asking for a message box with more options than OK that you can set. Id, say four would be optimal.
