Were the voice quotes hidden in the software or added by you?
I hear the game getting confused and playing the "Death Save" sound when you were in World Premier mode.....or was that something you added?
I'm sure I would be all over this (to try) if I still had my LAH. My only criticism from your initial list of things done / to do is....it seems like you are only making changes that make the game easier and I have never heard anyone criticize LAH for being too hard in the first place.
If I still had mine or the rules were fresher in my mind I'm sure I would have some suggestions. I'm sure other owners will have a lot of other cool ideas to try.
Good luck on the game changes.
