C2 is very fast when it comes to making games. The work flow is fantastic. However, there is one thing that I would really like to change. It would speed up production quite a bit.

If we could change this to any other sprite or game object this would be fantastic. As you can see in the example if I had to copy and pasted that out to let's say 10 or 20 game objects it would take a lot of time.
I suggest being able to drag it from the objects menu. And once you have the object you want you can push ctrl then drag that object and relplace it with others.
