Users on the Enterprise package are now able to create Draft versions of Playbooks and Cards! Draft items can only be managed by the owner/author of the playbook or card.
How to create a Draft Playbook:
Click "Create a Playbook" from any screen to get started
Add your title, description, and category
Click the arrow (^) next to "Create Playbook"

Select "Create Draft Playbook"
Click to confirm
That's all! You'll be directed to your new Draft Playbook, where you'll see "Draft" denoted underneath your playbook title, to the left of the description

To create a Draft Card:
Click "Create a Card" from any screen
Add your title, description, tags, and any resources you'd like
Click the arrow (^) next to "Create Card"

Select "Create Draft Card"
Click to confirm
That's all! You'll see "Draft" denoted above your card title
To edit a draft playbook or card:
Click "..." on your Draft Card or Playbook and select Edit
Make any changes you'd like
Click the arrow (^) next to Save & Make Live

Select "Save Draft Card" to keep your card in Drafts (make sure to select this option when you edit your card or Playbook if you're not ready to make it live!)
Click to confirm
Note: When you make a playbook live, you don't have to worry – any Drafts cards will still be in Drafts, and will not switch to live. They'll only be visible to you until you choose to make them live for others.
