Thanks @Jules and all for the discussion and information. Unfortunately, I don’t have information beyond what’s here: (Introducing Snapmark (September 2018)). There are a lot of factors that go into setting up testers with this experimental feature. The engineering team is determining each step of the rollout. If we do make it available to everyone, or if your machine is chosen for the rollout during the testing phase, you’ll see the Snapmark icon appear in your Workspace. In the mean time, keep an eye on the community for more information.
