The best feature in this software is its user-friendly interface that makes me feel more comfortable about using it compared to other similar softwares I have used before. It also provides very clear explanations regarding how things work so there are no problems for users who don't know much of what they're doing at first time use. There was nothing bad enough from my experience as far as complaints go but maybe you might want to consider having some tutorials available if your target audience consists mostly of beginners when using such programs for modeling purposes like myself. As mentioned earlier, one problem we had while trying out this product is where our own team members felt confused since not all features were explained well by us (ourselves). Also, some parts can be confusing even though after reading several times, we still couldn't fully understand everything related to certain concepts.
