Drafts and Working Copies
When you edit an asset, Cascade CMS automatically saves a draft of your changes. Drafts allow you to preview your changes as you make them without having to manually save a new version of the asset each time. This is especially useful for assets which require workflow, because you can edit and preview the asset as many times as needed before submitting it into workflow. You can preview those changes before submitting them by clicking Show Edit Preview (for page assets) or Preview Draft.
When viewing an asset you have a draft for, you'll be shown your draft first if it's newer than the current version. You can switch to the current version using the dropdown next to the title. You'll also be reminded if you start to edit an asset you already have an existing draft for.
You can see all of your existing Drafts on the dashboard in the My Content widget under Drafts.
