I've been using the beta with no issues so far. The "mold" feature is amazing! Thanks for including it. In it's current state it does have limited functionality though. A simple addition would really make this a stand-out feature: add a setting to split the mold in two pieces with a wavy line. This would allow for easy de-molding of the object as well as registration for the mold halves. Please consider! Also, I'd also like to see the addition of user add/delete supports. Thanks!!
