Here are some helpful resources as Marketo continues to roll out Sky features:
I've noticed the same thing Dan calls out - about the missing information. But I do use Skye occasionally for the saved filter set capability. I just select the saved filter set and then go back to the regular UI to continue.
I've tried it a few times after they released the beta this summer, but it was too buggy to be productive, then I recently tried again after they launched it with the latest release, but I'm finding there's still a lot of features that are still "Not yet available in Sky." So I'm going to wait it out a little longer before diving fully into it.
