I'm looking at herolab for use in a 3.5 game and wondered if anyone has opinions on it.
The UI looks the best and the authoring kit is very intriguing.
I know you asked for Hero Lab in a 3.5 game, but I can only comment on Hero Lab for a Pathfinder game. It works very well in my opinion. Super easy to create a character in, very little learning curve. If a bug is found they are very quick to issue a fix if reported on their forums. Seems to be a pretty good app.
