Hi guys,
Thanks for trying out this feature, seeing some great examples already!
I head a great time building it (was part of a research sprint, aka do whatever you want but deliver something awesome/useful)!
As @ahoeben indicated, this will be in the 3.2 (beta) version of Cura, which is due in roughly 1 week. The stable version will go out about 2 weeks later.
We're very interested in hearing how we can improve this feature in the future as well!
