I think the Serenity RPG sheet is very good currently and with a few minor tweaks and corrections would be perfect. The Die values for the dropdowns when going above d12 should be: d12+d2 d12+d4 d12+d6 d12+d8 d12+d10 d12+d12 Instead of d12+4 etc. Having a button to Roll two of these number lists besides each other would be great too since currently nothing on the sheet is roll-able. Just one button that can be customized for each roll should be enough. The game works like this, but I understand pulling the values from Specialties and generals would be very difficult to code, so just a roller with all of the die value options would be amazing for running this game!
