The ability to have multiple users who can access their own account without having admin privileges enabled was very helpful when we had our first child join us as well! We also love how easy it would be for someone with little computer knowledge or experience (like myself) could easily learn all of its functions within minutes - just by watching tutorials online!! I wish there were more options available in terms like fonts used etc but this has been addressed since then so not much else really comes up at times unless you're looking specifically into those areas which isn't too difficult once one gets familiarized wih them though :) Really nothing negative about unityvine itself other than maybe some minor bugs here &there from time-to-time depending upon your internet connection speed?
