I just tried Realtime Board and it made me love it. It's an excellent idea and very user-friendly.
I've found something that could make it even more friendly:
When you select an object, a toolbox with the utilities for this type of object may be shown automatically.
This way you don't have to search with the mouse the small settings button and click there, so you got in a simple touch every property you may want to modify in the object you've chosen.
Thanks very much and go on.
