That's certainly a more professional way to do it, I like.
Was there anything else? I think some had some suspected that the probabilities displayed on spells/saving throws were wrong.
From the numbers as such I just checked, they seem alright -- I just tried to cast Bane and Charm Person with Shadowheart on a bunch of goblins with CHA 8 each (-1). The DC of her spells is 13, so for the necessary CHA saving throw they needed to roll a 14 each. When casting Bane, one goblin actually succeeded in rolling exactly a 14, the others not. This would be a 35% chance for the Goblins to succeed, ergo a 65% chance of success for Shadowheart.
edit: Unsuccesful throws should arguably been shown in the log too. This currently also applies some for concentration checks, only if concentration is broken, is the saving throw shown (or is it actually vice versa?).
I'd also strongly urge to make no-damage rolls not look like misses in some way, because misses they aren't.
