I think it would be totally awesome if you could setup a sound effect to go along with a macro. Like when you attack have it make the sound of your weapon clashing against armor, I think this would have lots of possibilities. Also another neat idea would be triggerable sound effects set up if a token moves over a trap or something and the token representing the trap could automatically flip over to show the trap. Yet another idea along with this would be to be able to drag and area selection tool over an area to create a token , and then maybe a popup box shows up and asks you to upload a graphic for the reverse side of the token.
