I thought this was going to be great, I could declutter my Group Upload by creating separate boards. However, when I copied several slides from Group Upload to VBS 2017 and then removed them from Group Upload, they disappeared from VBS 2017 as well. That's not exactly what I had in mind. I also could not figure out how to import new media directly into any board other than Group Upload.
Bottom Line: Good start, needs some work.
