Wow, Workflows is a fantastic idea. I've created one that walks me through my typical sermon study process, and I've enjoyed it.
I have two suggestions for improving Workflows.
First, when a Workflow saves, it could include (as an option) the entire layout, which would streamline opening the Workflow from Home. I've saved the layout under a specific name, but then the button the Home page doesn't actually do much for me.
Second, please allow users to place saved Layouts on the Home page. At this point only quick start layouts can be added, and that's a shame.
