SW2020 what are your favorite enhancements

Looking for what is new is SolidWorks 2020

what we get... what we like.... why did they add that......what are we loosing  

Just made it to a roll-out event and there are some neat things.  Nothing was mentioned about what we are loosing, nor all of the many enhancements that have been added or not added.  

Tell us what your Favorite Enhancement was that made you want to jump out of your seat and yell hell ya at the event or that you have found that makes you really happy.
