I just barely found out about Roll20 and am starting to check it out, especially with regard to my favorite RPG (which I wrote and published), Dream Factory. Dream Factory RPG uses different six sided dice for different things. There are base dice, which have one color, and edge dice, which have another color and get swapped back and forth between the players and the GM. It's very important to be able to distinguish instantly between Base Dice and Edge dice, regardless of where on the table they are. Is there a way to have dice on the tabletop screen that are rollable and different colors? Also, minor question - when putting dice on the table is there a way to align them to the grid? Thanks.
