I'm thinking to upgrade to Marvelous Designer 7 but not sure if it's worth it. Are the new features really a big time saver? Do you find it helps speed up your workflow?

I'm particularly interested in the Marvelous Designer 7 feature of the ZBrush bridge and the Flattening tool but I've been hearing a lot of people say they don't work. 

What do you guys think of the new Marvelous Designer 7 features?

Feedback please!
