@frikkr lol it was just a suggestion because the new courses are coming pretty soon, but 2.8 ROCKS so I don’t blame you 😉
Collections are indeed a new and improved layer system with a lot more features. The Blender Manual on collections can explain it better than me 😊 but they are definitely more like a normal folder structure and they are the best!!
Since you are just starting out again, I would actually suggest to start a fresh project, because old files usually don’t transfer well to 2.8… it probably would save you quite a headache to not try to get your old stuff to work. How about joining us in the vehicle community challenge I’m hosting this month? Just create a simple scene you’re comfortable with and have fun exploring 2.8 😄
File -> Defaults -> Save Startup File (according to the manual)
Hope this helps!
