I noticed you updated the die roll system in beta 3 - when a user is prompted for values - by including both the options for adding to each die rolled and adding a value to the total result. Thanx for updating that feature.
What I need is the following (please fill in the blank):
Number of Dice rolled = $nDice$
Number of Sides on each die = $nSides$
Number added to each die = ???
Number added to final result = $plus$
