Celtx now has a Drafts feature, included with all paid plans. Users can create a Draft from all their Film & TV scripts to save important versions of their scripts, stash a different plot arc, etc... Each draft will have its own script history, like with all other scripts. Here's how it's done:
- Under the file menu in the Film & TV script editor, select the 'Save as Draft' option.
- From there, give the draft a name and click save to complete the process. You will have the option to load the draft, or, continue editing your main script.
- All of your drafts for your project will be placed under your drafts folder. Please note: If you have no drafts, the folder will be hidden.
You'll be able to identify you're in a draft by the grey banner in the name, in the top menu
Also, drafts have the option to create a project from that script, or, to delete the draft itself:
