All right during my recent game I cam across to things that would make the system easier. The first is a whisper tab. That way you can keep your whispers separate from the actual dialogue. Having several conversations going on in one area can get a little confusing.
The second one has to deal with the die roller. One thing that would be really helpful is the ability to place in modifiers (which change depending on several factors in any game) in your die rolls easier. For example being able to make a Die roll like 1d20+5+? you can have a die roll where with the question mark a separate box comes up so you can add a modifier to like a -2 because of (insert something) or a +4 because of someone's special ability to give you a bonus. Having to either remember the modifier is there or to have to have a roll that you use often can become tiresome.
