roll20 has great rolling strings for things like rerolling 1s. Would be great in the new d20 sheet to be able to enter a die string for attacks and damage instead of having to pick a die face and number separately with no "markup" allowed. e.g., go set up the attack entry for a monk with tavern brawler and eliminate any manual rerolling. Thanks! Similarly, effects that modify damage could invoke rerolls or do other things to edit the dice string. e.g. toggling on a damage effect "r1" doesn't work, but could be good
