May I make a request for the list?
The Adventure Game Engine uses a pretty simple "3d6 + modifiers vs. target number" system to resolve dice tests. Nothing MW can't handle currently.
The secret sauce happens whenever doubles are rolled. At that time you reference the "stunt die," which is one of the three d6's that is differently colored (or otherwise differentiated). The number on the stunt die generates points for special maneuvers or gets used for determining degrees of success. It is occasionally necessary in this system to reference the stunt die even when doubles are not rolled.
As it stands now I think it's perfectly feasible to roll 2d6 and 1d6, the latter die being your stunt die. You would just manually total all three and manually check for doubles for your result. But it would be nice to get Dice Tower integration if that's possible.
For this to work on the site I think the Tower would need to report which dice is being differentiated in the results. Some ideas, the stunt die is indicated in brackets:
Here's a version where maybe the tower recognizes the doubles rolled.
